An app that can generate 64,000 kosher cheesecake recipes aims to prove AI’s value for Orthodox Jews

(JTA) — Sara Goldstein’s regular cheesecake recipe is like the rest of the kosher food she makes and shares on her Instagram account — “straightforward, and I wouldn’t say too adventurous.”

But she tried something special this year ahead of Shavuot, a Jewish holiday that begins Thursday night, when dairy foods are traditionally on the menu. In honor of the holiday, she whipped up a bourbon caramel cheesecake, with candied pecans on top.

Goldstein’s baking shakeup was spurred by an online tool that, using artificial intelligence, allows users to mix and match ingredients that can be made into more than 64,000 different cheesecake recipes. For Goldstein, a chef and kosher recipe developer who lives in Lakewood, New Jersey, CheesecakeWizard.AI offers a welcome challenge.

“You have to be extra creative in the kosher world because it’s very limited,” she said. “And I think it definitely opened people’s eyes to what’s possible. I mean, saying there’s 64,000 combinations that are kosher —  it’s really, really cool.”

The app’s creator, Brooklyn marketing executive Avi Bree, doesn’t just want to push the bounds of what gets served on Shavuot tables. He’s also looking to prove to clients his value in a world of AI-generated press releases — and to show his fellow Orthodox Jews that ChatGPT and other AI tools can be a boon to Jewish observance, not a threat, despite concerns about internet use in his community.

“Not everybody who is going to go to this website is actually going to actually bake the cheesecake,” Bree said. “They’ll futz around with it, and they’ll push a couple buttons and it’ll make us all meshuggeneh trying to come up with the craziest flavor.… While they’re doing it, the company that’s sponsoring it, their logo and their name is there.”

The app asks users to select their crust, filling and topping preferences, then uses artificial intelligence to spit out a recipe to match. An image integration feature called Midjourney allows users to see computer-generated pictures of what their cheesecakes might look like — from carrot-cake crusts to maple and sweet potato filling to savory toppings such as an olive tapenade.

Since its launch last week, Cheesecake Wizard has been used by about 12,000 people to generate 45,000 recipes — though it remains to be seen how many actual cheesecakes result. Bree said that like Goldstein, he had been drawn to the “boozy options” in the Cheesecake Wizard interface and hoped that when the holiday begins Thursday night, he’ll get a chance to partake.

“After a very long week of work, I’d like to sit down on Shavuos eating cheesecake, and having a splash of bourbon on top would definitely, you know, add a little more enjoyment to the holiday festivities,” he said.

Bree’s experiment with AI started last spring, when clients began to drop him because, they said, they could use the new technology to create their marketing materials instead. He decided to explore the new terrain. Passover was approaching, and Bree’s first venture was a day-trip generator, inspired by the hassle Orthodox families can face when deciding what to do in the middle of the weeklong holiday, when Jewish schools and workplaces are closed.

CanWeGoNow launched on the first day of chol hamoed, the period of the holiday when travel is allowed, and quickly crashed as the link ricocheted across WhatsApp groups that are the primary form of communication for many Orthodox Jews. Bree called his wife from synagogue and said he needed to scrap their own family’s plan to take their six children to an amusement park. He had to spend the time getting the site back up.

“I said, ‘Pessel, the bottom line is I stepped into something that might be amazing,’” he recalled. “I generally don’t work on chol hamoed, but if there’s a loss involved, the rabbinical leaders say you can work. So I said, ‘If I don’t take care of this, the whole thing’s going to fold.’”

Ultimately, 20,000 people generated tens of thousands of trip ideas in the United States, Israel, England, Australia and even Mexico, where hundreds of people at a kosher-for-Passover hotel got wind of the app.

Bree lost money on the venture, but he gained confidence that AI could catch on in his community, despite some of his Orthodox peers’ ambivalence toward new technologies. Now, he has relaunched his marketing firm to focus squarely on using AI to reach Orthodox audiences. (Its name, MarketAIng, makes the gambit visible.)

“The Jewish community is always a little bit behind, let’s just face it,” he said. “Our tradition is what kept us going all these thousands of years, so anytime something new comes into the picture, we’re always a little more wary and always a little more concerned. So AI really hasn’t made inroads yet.”

Bree’s latest effort hit a turning point while he was in synagogue, which he referred to as “a mini-networking event” that he attends three times a day for prayers. A self-described ultra-Orthodox Jew, he had been casting about for a kosher corporate partner for the cheesecake bot. An acquaintance named Akiva overheard him lamenting his lack of connections to a fellow worshiper after evening services.

Akiva said his wife worked for a kosher dairy-products company called Norman’s. A few WhatsApp messages later, Bree was in touch with executives there — and now the company’s name and logo appear on the website, and its products are inserted into the cheesecake recipes that the tool generates. Goldstein has also promoted the company on her social media posts about Cheesecake Wizard.

The sell wasn’t totally straightforward, Bree said. An executive “was a little bit nervous because of the internet aspect,” he recalled. “Right now in the Jewish community, it’s a weird sort of policy we have, like, we don’t encourage you to use it but if you’re going to use it, have a filter on it.”

Indeed, internet use has been a fraught topic in haredi Orthodox communities, with rabbis warning that online access can be a gateway to inappropriate content that conflicts with and diverts attention from Jewish practice.

Some Orthodox leaders have urged Jews to reject the internet entirely. In 2012, a rally warning of the dangers of the web drew more than 40,000 men to Citi Field in New York; last year, two massive rallies for women urged them to delete their social media profiles and give up their smartphones.

With the abrupt arrival of consumer-facing AI in recent months, the technology has drawn specific attention from some rabbinic leaders for the first time. Last month, a dozen rabbis from the traditionalist Skver Hasidic community, based in New Square, New York, explicitly banned its use.

“It is possible that at this point, not everyone knows the magnitude and scope of the danger, but it has become clear to us in our souls that this thing will be a trap for all of us, young and old,” the rabbis wrote in their decree last month. “Therefore, the use of ‘AI’ is strictly prohibited in any shape and form, even by phone.”

Despite these warnings, many haredi Orthodox Jews use the internet for work, shopping and other activities. But in some communities, users are expected to install “kosher” filters that block content considered inappropriate, and many Orthodox yeshivas require parents to install filters as a condition of enrollment. Bree said his own children’s Brooklyn yeshiva required a phone filter, which he installed, and that he made sure to construct his apps so that they would function on phones whose function is limited to WhatsApp and basic communication tools.

He also said that while Norman’s was persuaded to move forward with the cheesecake app because it had its own website, he was considering adding a disclaimer.

“We might have to actually make a little statement on the website saying something along the lines of, you know, ‘Please abide by your rabbinical guidelines regarding internet use,’” Bree said. “Because people were saying, ‘Oh, what are you pushing internet for?’ We’re not pushing it. If you’re using it anyways, then you could use this.”

Goldstein said she wasn’t sure she would become a regular AI user but thought that Cheesecake Wizard, for which she posted an instructional video for her followers on Wednesday, was a comfortable entry point for her community. “I definitely think it’ll take people a little while, maybe, to warm up to the concept, but it’s a great way to introduce it,” she said.

In her heavily Orthodox town of Lakewood, Goldstein said a wide range of internet uses are tolerated — and that she sees a value in remaining online.

“I’m not telling people to come start using Instagram, start using AI — it’s if you’re here [and] it’s where you’re at, then this is a fun way to make something amazing, to elevate something for chag,” Goldstein said, using the Hebrew word meaning holiday. “For people who are already out there on the internet — whether you need it for work, or just, you’re not at that place yet to completely eradicate internet from your life — here’s a way to take these tools and do something even spiritual with it.”

California Jewish groups decry antisemitic conspiracy theories printed in governor’s race voter guide

(JTA) — As Californian voters checked their mailboxes this week, they found a voter guide containing conspiratorial claims about Israel and antisemitic rhetoric.

The mailer, which was sent by California Secretary of State Shirley Weber to the households of all registered California voters, featured biographical information about candidates slated to appear in the state’s June primaries. In all, there are 32 candidates listed, of whom 10 are considered serious contenders.

Among those who are not: the far-right activist Don J. Grundmann, who is not affiliated with any party and has previously described a group he was affiliated with as a “totally peaceful racist group.” Grundman used his entry in the guide to promote a series of anti-Israel conspiracy theories and antisemitic rhetoric.

His entry claimed that Israel had been behind the murder of conservative activist Charlie Kirk; purposefully killed U.S. soldiers during an attack on the U.S.S. Liberty in 1967; orchestrated the 9/11 attacks and planned to “suitcase nuke” the United States.

“Israel, the REAL terrorists, created and funds Hamas via Qatar,” Grundmann wrote. “Countless war crimes by lsrael/ Netanyahu. No further funding for Israel. They call Palestinians AND Christians AND America ‘Amalek;—their sworn forever enemy.”

The paragraph, which included a series of links to websites promoting antisemitic materials, also included a series of antisemitic claims about Jewish supremacy.

“We are ‘goyim’ (less than human animals/cattle) that they will enslave. We are stupid chumps,” Grundmann wrote, using the Hebrew word for non-Jews that has been increasingly used by the far-right. “Israel rules our conquered Republic. Talmud—their Bible—says Christ boiling in in Israel allowed/planned/promoted Hamas attack (they murdered their own people) to justify genocide and steal billion$ in Gaza oil/gas rights. Christian Zionism = soul poison. Talmudic Judeo-Christian values’ don’t exist . . .”

In both the print version delivered to voters and the online version of the voter guide, a disclaimer was added for Grundmann’s entry that did not appear for any other candidates: “The views and opinions expressed by the candidates are their own and do not represent the views and opinions of the Secretary of State’s office.” The line also appears on the bottom of each page.

Local Jewish groups, including the Jewish Federation of Orange County, decried the inclusion of the entry, saying in a letter to Weber, “When something appears in an official voter guide, it carries a level of legitimacy and reaches millions.”

Added the groups, including the federation, the Anti-Defamation League of Orange County/Long Beach, the Jewish Community Action Network and Israeli American Council, “By including a statement containing antisemitic tropes and conspiracy theories in an official voter guide, the State has effectively provided a government platform for rhetoric that fuels division and undermines the safety and dignity of Jewish communities.”

The groups called on Weber to explain how the statement was approved. They contended that the entry violated the guidelines by making “extensive reference to third parties” and using “largely of inflammatory and conspiratorial claims unrelated to any permissible category of content” included in the provisions.

“At a time of rising antisemitism, including rhetoric rooted in antisemitic tropes in a state publication is deeply concerning,” read the letter. “This isn’t about limiting speech—it’s about enforcing neutral standards and maintaining the integrity of our election materials.”

The voter guide comes as antisemitism has emerged as a notable issue in the upcoming California governor’s race, with several candidates staking out their approach to rising antisemitism in the state at a candidate forum in February. The primary is on June 2.

Matan Koch, disability advocate who urged Jewish communities to ‘let everyone in,’ dies at 44

(JTA) — Matan Koch needed little introduction as he rolled up to the podium to speak at his synagogue’s Disability Shabbat service in October. His wide smile and power wheelchair made him well known to many his Los Angeles congregation, Ikar.

Still, Rabbi Sharon Brous, beaming at him, described her congregant warmly before ceding the microphone.

“The most important thing for you to know about Matan is that he is a deeply soulful, profoundly decent, and incredibly kind human being. And every single day that you have been in our community, you have made our community better,” she said. “It’s an absolute joy and honor to dive in with you, to call you a friend, and to have you as a beloved member of our community.”

In the sermon that followed, Koch described times that he had felt excluded from Jewish communities, or struggled to be included, because of his own disabilities. He urged his fellow congregants to change the way they think about inclusion.

“Every time you’re looking for one more participant, one more volunteer, one more Torah reader, think about who is excluded from our community by disability or any other reason — and think about how we would be enriched if only they were here,” he said. “Then let that motivate us to create an inclusive community that truly lets everyone in.”

It was a synopsis of the mission that Koch carried with him in his personal and professional life. Koch, who used a wheelchair throughout his lifetime, and who was respected as an accomplished lawyer, a passionate advocate for people with disabilities, and a committed member of Jewish communities, died Friday in Los Angeles, after a brief but fierce battle against stomach cancer. He was 44.

“His condition declined far more quickly than he, and we, had hoped,” his family wrote as they shared the news of his death on his Facebook page, filled with remembrances from hundreds of friends and followers from across the country.

“Ever optimistic, he pushed to squeeze every drop of love and connection and intellectual engagement out of life,” they added. “Even as options narrowed, Matan remained focused on staying present and connected to the people he loved.”

At the time of his death, Koch was the Los Angeles’ ADA compliance officer and director of its disability access and services division, ensuring that the city comported with the requirements of the 1990 Americans with Disabilities Act.

In the last post he authored earlier this month, Koch expressed both anger about his illness and appreciation for the many people who were contributing to a crowdfunding campaign to allow him to die with dignity at home. He said he was feeling “fury that my life has been cut so tragically short, euphoric overwhelming at the outpouring of love and support, and awe and gratitude for my family as they work with all of you in a full court press to see my needs met.”

Born in 1981, in New Milford, Connecticut, Koch was both brilliant and precocious and from an early age moved through a world not built for his body with clarity and determination, according to Rabbi Shira Koch Epstein, one of his four siblings.

Born prematurely, he had cerebral palsy, a neurological condition that severely limited his mobility and required him to use a wheelchair.

It was just a few years after the passage of the Individuals with Disabilities Education Act, which reshaped the requirements for schools to serve students with special needs. Yet his parents, the late Rabbi Norman Koch and Rosalyn Koch, a Jewish educator, had to fight for services from their local public schools.

Koch advanced to Yale University at age 16 and went on to Harvard Law School when he was just 20, graduating in 2005. He held numerous appointments on disability rights committees, first at Yale and then as vice president of the New Haven Disability Commission. In 2011, President Barack Obama tapped him to serve on the National Council on Disability.

“His whole life was breaking glass ceilings,” Epstein told the Jewish Telegraphic Agency in a phone conversation just hours before Matan’s death.

“He had a body that was built for a world that doesn’t yet exist and he spent his whole life working to build systems that recognize ability, expand access and include people across the full spectrum of disability,” Epstein said, adding, “He sees the goodness in every person he meets, and he sees the possibility.”

The family of five kids grew up in a deeply Jewish home. Epstein recalled her younger brother having deep conversations about Jewish values and ideas with her and their father.

“That was something very important to Matan. He really loved to learn and loved to sing. He sang with gusto. And he loved camp,” added Epstein, who serves as executive director of Atra, the Center for Jewish Innovation.

Their parents were leaders at Camp Eisner, the Jewish summer camp in the Berkshires, and the family spent their summers there. “The Jewish community is his home,” she said.

Rabbi Jonah Pesner, director of the Religious Action Center of Reform Judaism and senior vice president for the Union for Reform Judaism, was the director of education at Camp Eisner when Koch was a camper. He recalled a time when Koch asked Pesner to help him to go to the bathroom.

Koch led Pesner back to the bunk and explained step-by-step, how to assist, with laughter and without making Pesner feel self-conscious. “From the earliest age, Matan was engaging, mature beyond his years and non-judgmental,” Pesner said.

After graduating from law school, Koch worked first as an associate at major law firms before striking out on his own as a consultant working to help businesses and nonprofits become more inclusive. From there, he joined a disability rights organization called Respectability, moving to Los Angeles to become its local director.

Many people assumed that because he was quadriplegic, Koch must be helpless, according to Jennifer Laszlo Mizrahi, the Jewish activist who co-founded the group, now known as Disability Belongs. In fact, she said, his abilities were remarkable.

She recalled the role Koch played during the Covid-19 pandemic, a perilous time for people with disabilities, who faced high mortality rates if they became ill from the virus.

Many of his staff were disabled. They — and countless other disabled people — couldn’t risk going to a grocery store before vaccinations were available.

Koch’s team partnered with Los Angeles and the federal government to change the regulations to allow SNAP beneficiaries to have their groceries delivered in California and in several other states. “That was huge,” Laszlo Mizrahi said.

In Los Angeles, Koch was an active and beloved member of Ikar. In his Disability Shabbat sermon, he recalled an experience in college that led him to take a deep dive into a Talmudic debate on excluding people who might be distracting from leading the priestly blessing, he told them. Ultimately, the rabbis reasoned their way into acceptance.

“In using that text, Matan acknowledged the reality of how a community might interact with someone with a disability,” recalled Morris Panitz, the congregation’s associate rabbi. “People might be uncomfortable at first. But the work of the community is to get to know the person.”

Koch delivered his sermon with conviction, but gently, with his warm smile, Panitz said. This was true of him generally. “He invited people along for the journey,” he said.

“Matan Koch left an indelible mark on our community,” the synagogue told its members in an email on Sunday that added, “Matan’s persistent belief and tireless work to ensure that everyone feels welcomed and known will endure as a moral vision in our community. We will miss Matan’s enthusiastic davening, wide smile, and generous love.”

Koch could hold court in meaningful conversations as easily with heads of businesses as with Jewish texts, said Jack Rubin, one of his closest friends since they met their first week at Yale. Until Koch could not anymore, they talked for hours at a time.

“Nothing was outside the bounds of his intellectual curiosity or his capacity to wonder,” said Rubin, whose family spent the first of Passover with Koch at Koch’s home earlier this month.

“We had seder with him, for as long as he had the energy. He asked my kids questions. It was amazing,” Rubin said, holding back tears just a few hours before Koch died.

Although Koch possessed a unique ability to persuade people to embrace inclusion and implement meaningful opportunities for disabled people, according to those who knew him well, he did face limits in his own life.

At one time, Koch hoped to attend Hebrew Union College and become a rabbi, Pesner recalled. He and others tried for a long time to make it happen. But Koch’s complex medical needs couldn’t be overcome within the school’s physical and programmatic constraints at the time.

“It’s the biggest regret of my career that we could not figure out how to get him rabbinic ordination,” Pesner said. “I think it was a loss for the Jewish people.”

Yet Koch never stopped pressing Jewish communities to rethink how they treat members with disabilities, challenging up-and-coming leaders at the Reform movement’s youth conference and being honored in 2016 by the Jewish disability inclusion organization Matan.

“Sometimes you can be a change-maker and be a person who’s putting out really big ideas, but sometimes it can come with a sharp edge,” Rabbi Rick Jacobs said in a movie compiled to honor Koch at the time, which also included a tribute from the actress Mayim Bialik. “With Matan, it comes with love, and he raises people up.”

Meredith Polsky, the director of the organization Matan, said in an email that her group would continue the mission of the friend and advocate who shared its name — a name meaning “gift” in Hebrew.

“Though his final breath came far too soon, we carry that charge forward, committed to building a Jewish community that reflects his vision of true inclusion and belonging,” Polsky wrote.

Koch’s father Norman died in 2015. Koch is survived by his mother, Rosalyn Koch, siblings Rabbi Shira Koch Epstein and Jason, Yonatan Koch, Adina Koch and Aytan Koch; nieces and nephews Amichai, Kobi, Avigayil, Duncan and Jason and his honorary family: Martin Smith, Jack and Stephanie Rubin and their children Olivia and Edward.

Assault outside synagogue and rock thrown through Judaica shop window ratchet up Toronto Jews’ concerns

(JTA) — A pair of incidents took place outside of Jewish sites in the Toronto area over the weekend, adding to a series of attacks that have left the city’s Jewish community unnerved.

During Shabbat services on Saturday, a man tried to force his way into the Sephardic Kehilah Centre, in the suburb of Vaughan. After the man was turned away by security, he reportedly encountered a father and son on their way to the synagogue and punched the father in the face. The father was left with no serious injuries.

The following day, photos circulated after a rock was hurled and broke the window of Aleph Bet Judaica, a shop on the heavily Jewish Bathurst Street corridor. Police did not confirm which business was hit, but confirmed that a rock was thrown at a business near Bathurst Street and Regina Avenue, and that the Hate Crime Unit “was consulted and is aware.”

No suspects have been identified in either incident.

Unlike other recent attacks on Toronto synagogues and Jewish businesses, which were carried out late at night, these two incidents took place in broad daylight, both around 9:30 a.m.

The UJA Federation of Greater Toronto wrote in a statement that the Sephardic Kehilah Centre incident, which is being investigated by the police’s Hate Crime Unit, reflected “a continued pattern of antisemitic violence targeting our community.”

In March, three synagogues across the Toronto area were hit with gunfire. In the last couple of months, a restaurant owned by a Jewish pro-Israel advocate was shot at twice, at two of its locations. And in 2024, a Jewish girls’ elementary school was hit by gunfire on three separate occasions.

“As these incidents become more normalized, they erode public safety and our way of life as Canadians,” the UJA’s statement read. “This cannot be tolerated.”

The Canadian Jewish News reported that the suspect was turned away by synagogue security on Saturday for “suspicious behavior,” according to an email from the rabbi, and told security that he was Middle Eastern and not there for prayer services. After the man left the building, according to the email, he threw away torn pieces of paper which looked to contain verses of Psalms.

B’nai Brith Canada blasted “people in positions of authority” who it says have “responded with hesitation, weak enforcement, and political platitudes while Jewish communities continue to pay the price.” It also thanked Vaughan Mayor Steven Del Duca, who wrote that “we must be vigilant and do everything possible to support and protect our Jewish residents.”

The group called for the federal government to take eight specific actions to combat antisemitism, including establishing a national antisemitism task force, providing emergency funding for the protection of Jewish institutions, and prosecuting the repeated gunfire attacks as acts of domestic terrorism.

On Monday, B’nai Brith also released its annual audit of antisemitic incidents, which found that there were 18.6 antisemitic incidents reported per day across Canada in 2025, a 9% increase from 2024.
