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.”

Rep. Jared Moskowitz becomes latest Jewish lawmaker to reveal antisemitic threats
(JTA) — The messages that Rep. Jared Moskowitz said he received at his office were filled with obscenities, calls to “kill Jews” and warnings that the Florida Democrat would be “going down.”
Moskowitz played the voicemails during an interview with CNN’s Sara Sidner on Friday as he described a sharp rise in antisemitic hostility against Jewish lawmakers since Oct. 7, a trend he said reflected a broader normalization of antisemitic rhetoric in American public life.
“We seem, Sara, to have passed a Rubicon now with these antisemitic threats,” Moskowitz said. “It used to be once in a while you’d see a swastika on a building, once in a while, you know, someone would say something online. Now it’s every day, all the time, on podcasts, online, in the media, in the halls of Congress, and they’re trying to get Jews.”
CNN played multiple messages that illustrated Moskowitz’s point, with Sidner warning viewers that what they would hear was “deeply disturbing.”
Moskowitz, who is Jewish, said the spate of threats had caused him to need a police officer stationed outside his home 24 hours a day, since a man was sentenced to prison for plotting to kill him in November 2024.
“The U.S. government needs to kill Jews, you kill these f–cking nasty Jews, kill every single f-cking Zionist scumbag,” a caller said in one of the voicemails. “Zionism is treason to ‘we the people’ in our U.S. Constitution. Kill Israel.”
Another caller left this message: “Hey you Zionist Jew f-cking pig. How about no more money for Israel? Funding Israel, stealing more of our money for Israel. F-ck Israel, let them f-cking burn to the ground. You’re going down too, sir.”
Moskowitz is far from the only Jewish lawmaker to report a rapidly increasing number of antisemitic threats and harassment in recent weeks. The shift comes as both parties grapple with internal tensions about how to handle antisemitism within their ranks, and as anger about Israel and the Iran war funnels more attention to U.S. Jews. It also comes amid rising political violence in the United States.
“It’s no longer a Republican and a Democrat [issue],” Rep. Max Miller, a Jewish Ohio Republican, told Axios this week. “Both ends of our parties are wackadoos who hate Jews.”
Miller received a message warning that “antisemitism is on the rise because you guys think you own the f-cking world,” according to Axios, which said the caller added, “You guys are going to be shot dead every f-cking day.”
Among the messages highlighted by a recent Axios report on the phenomenon was a letter sent to New York Democratic Rep. Jerry Nadler, in which one constituent wrote that “Hitler was spot-on, 100% right about the filth that you Jew-bastards, you kikes are.” In a voicemail left for Ohio Democratic Rep. Greg Landsman’s office, one caller said, “I don’t like Jewish people, and the congressman should just go die.”
The lawmakers say the phenomenon is new. “Across the board, we have never seen anything like this in my lifetime in public office,” Jewish California Rep. Brad Sherman told the New York Times last month. “It’s like you turned the volume up from two to 10.”
The volley of antisemitic threats has also spilled into the real world, with Miller reporting last year that a man had attempted to run him off the road while calling him a “dirty Jew.” Last year, a man set fire to the residence of Jewish Pennsylvania Gov. Josh Shapiro hours after his family hosted a Passover seder there.
“We need good people to not be quiet,” Moskowitz said when Sidner asked him what message should be sent in response to the rise in antisemitic rhetoric targeting lawmakers.
“There are people out there, they may disagree with U.S. policy, they may not like the leader of a country, but they shouldn’t be allowing antisemites into their movement,” Moskowitz said. “They should not be embracing this sort of behavior, because they’re trying to win some sort of political point. It should be obvious.”
Moskowitz’s comments echoed a growing debate over the normalization of antisemitic rhetoric within American politics on both the left and the right, with Jewish lawmakers and watchdog groups warning that language once relegated to the fringes has increasingly become mainstream.
Last week, Texas U.S. Senate candidate James Talarico told the Jewish Telegraphic Agency that he would not campaign with Maureen Galindo, a Democratic congressional candidate in Texas who says she wants to open a “prison for American Zionists” among other incendiary remarks. Talarico said in a statement that “antisemitic rhetoric has no place in our politics.”
On Wednesday, Sen. Rand Paul’s son William apologized after he made repeated antisemitic comments directed at New York Republican Rep. Mike Lawler, who is not Jewish, including calling Jews “anti-American.”
Moskowitz told CNN that, while people may criticize the Israeli government and Israeli Prime Minister Benjamin Netanyahu, the voicemails left at his office illustrated “how quickly, you know, they go from Zionism to Jews, Israel to Jews.”
“Listen, if you don’t like Netanyahu, great, go out and criticize him all day long,” Moskowitz said. “But don’t let people into your tent that you know are threatening to kill my family or my kids.”

Jewish groups denounce fatal shooting at San Diego mosque, say it proves need for security funding
(JTA) — Jewish groups are denouncing a fatal shooting at a mosque in San Diego in which three people, including a security guard, were killed. They are also saying the incident, which follows attacks on synagogues, underscores a need for more federal funding for security at houses of worship.
Police in San Diego said they are investigating the attack on the Islamic Center of San Diego as a hate crime. San Diego Police Chief Scott Wahl said two teenagers, ages 17 and 19, who appeared to have carried out the attack were found dead of self-inflicted gunshot wounds in a car nearby.
“We are heartbroken by today’s attack on the Islamic Center of San Diego. Islamophobia has no place in California or anywhere in this country,” Jesse Gabriel, chair of the California Legislative Jewish Caucus, said in a statement. He added, “We are committed to working with our colleagues to strengthen protections for houses of worship and combat hate-motivated violence.”
The attack, which occurred at about 12:30 p.m. local time, sent five area schools into lockdown, including a Hebrew charter school.
“We’re safe and we’re following the direction of the police,” a representative for Kavod Hebrew Charter School told the Jewish Telegraphic Agency by phone on Monday afternoon. Kavod is a non-religious bilingual K-8 school that employs a number of Jewish and Israeli educators.
A synagogue that houses a school in an adjacent neighborhood also said it was briefly locked down in the immediate aftermath of the shooting.
The mosque attack comes two months after a man rammed an explosives-laden truck into one of the largest synagogues in the United States, Temple Israel in Michigan. There, the synagogue’s robust security training was credited with halting the attack. Children were inside the adjacent preschool at the time.
“The images coming from San Diego are all too familiar to us,” Temple Israel said in a message to its community that it posted to social media. It said that one of its rabbis, Jen Lader, was in Washington, D.C., to lobby for $1 billion in federal security funding for houses of worship.
Jewish Federations of North America said it had more than 400 local Jewish leaders in Washington to lobby for the security funding, which it said was necessary to protect religious communities from threats that are “real, urgent, and growing.” The $1 billion ask is a centerpiece of JFNA’s response to growing security concerns and would represent more than a doubling of federal spending on security needs for houses of worship.
“To anyone who feels this is excessive, what happened to Temple Israel two months ago, and now, the Islamic Center of San Diego, proves that it is not optional funding,” Temple Israel said. “Every dollar will be necessary to protect houses of worship all over the country.”
Imam Taha Hassane of the Islamic Center of San Diego, which includes a mosque and the adjacent Al Rashid School, said teachers, students and school staff were safe.
“At this moment, all that I can say is sending our prayers and standing in solidarity with all the families in our community here, and also the other mosques and all the places of worship in our beautiful city,” Hassane said during a press conference Monday afternoon. “They should always be protected. It is extremely outrageous to target a place of worship. Our Islamic Center is a place of worship. People come to the Islamic Center to pray, to celebrate, to learn.”
Law enforcement across the country are tightening security measures in response to the attack in San Diego.
“While there is currently no known nexus to NYC or specific threats to NYC houses of worship, out of an abundance of caution, the NYPD is increasing deployments to mosques across the city,” the New York Police Department said in a statement.

Mamdani’s first Jewish Heritage event reveals a narrowed circle
The Jewish American Heritage Month reception at Gracie Mansion, the mayor’s official residence on the Upper East Side, on Monday evening felt unlike any before it. It was not simply because the host, Zohran Mamdani, is New York City’s first Muslim mayor or because the Shavuot-themed menu was dairy. It was that the annual gathering came amid one of the most strained relationships between a mayor and much of New York’s Jewish establishment in recent memory.
Even the setting reflected the changed atmosphere. Previous receptions under former mayors had spilled into a large tent in the mansion’s garden overlooking the East River, with buffet tables lined with kosher food, bars stocked with liquor and wine, live music and packed crowds of rabbis, communal leaders, elected officials and supporters mingling late into the evening. The longstanding traditional events became demonstrations of the close alliance with mainstream Jewish organizations and pro-Israel activists, who formed a key part of their political base.
This year’s gathering was different. The event was moved indoors to Gracie Mansion’s smaller blue reception room. The crowd of 150 people was served by waiters quietly circulating through the room with small dairy dishes in honor of Shavuot: miniature cheesecakes, halved cheese blintzes, cheese bourekas served with a touch of charif on the side, potato knishes, chocolate mousse, salad cups and cheese-ball skewers. The drink selection was limited to Herzog wine from California and water.
There was no music at all — not even a cappella — despite the easing of traditional restrictions during the final days of the Omer before Shavuot.
Mamdani’s Jewish commissioners, deputy mayors and aides circulated through the room, greeting attendees. But absent were prominent Jewish figures in city government and politics, including Police Commissioner Jessica Tisch, Comptroller Mark Levine, Manhattan Borough President Brad Hoylman-Sigal and most of the local elected officials. The only Jewish elected officials in attendance were Councilmembers Harvey Epstein and Lincoln Restler, and former comptroller and now congressional candidate Brad Lander.
The crowd itself reflected the Jewish coalition emerging around Mamdani’s mayoralty: anti-Zionist activists aligned with groups such as Jews For Racial & Economic Justice and Jewish Voice for Peace; liberal Jewish leaders affiliated with New York Jewish Agenda, who have sharply criticized Mamdani on Israel and antisemitism issues while continuing to engage with the administration, and those aligned with pro-peace organizations; and Hasidic leaders from the Satmar community in Williamsburg, who religiously oppose Zionism and have long shaped their relationship with municipal government around local priorities such as housing, education and nonprofit funding.
Mamdani was introduced by Phylisa Wisdom, executive director of the Office to Combat Antisemitism, who also serves as the unofficial director for Jewish affairs. Rabbi Irwin Kula, president of the National Jewish Center for Learning and Leadership, delivered the invocation, and Jake Levin, manager of the Mayor’s Office of Mass Engagement, served as emcee.
The mayor offered some greetings, describing the preparations for Shavuot across the city, the teaching of Jewish values and his administration’s effort to combat rising antisemitism. “Jewish New Yorkers have worked to cultivate a city that is safe and open to all,” Mamdani said. “You should be accorded the same security and the same peace of mind.”
He then honored Ruth Messinger, the trailblazing Jewish political leader who in 1997 became the first and only woman to win the Democratic nomination for New York City mayor and went on to lead American Jewish World Service. Messinger backed Mamdani in the mayoral race last year. Guests were then privately ushered in to take photos with Mamdani.
Mamdani’s coalition

The reception came just days after Mamdani reignited tensions with many Jewish communities by posting a Nakba Day video produced by his City Hall media team commemorating the displacement of Palestinians during Israel’s founding in 1948. That was followed by what was perceived as a delayed and balanced response to pro-Palestinian protesters descending on a heavily Jewish Brooklyn neighborhood where a synagogue hosted a real estate sale that included West Bank properties.
The Nakba video angered many Jewish New Yorkers who already viewed Mamdani’s sharp criticism of Israel and embrace of Palestinian activism as dismissive of Jewish fears over rising antisemitism. Despite the backlash, there was little indication that Mamdani intends to moderate the political identity that brought him to power. Mamdani defended the video Monday morning when pressed about the civic purpose of using official city resources to mark Nakba Day, saying that acknowledging Palestinian suffering does not negate Jewish suffering or Israel’s history. He also declared that his “door is always open” to Jewish leaders despite the backlash.
But on Monday, a notable array of prominent Jewish leaders did not walk in — or were not invited.
Among those absent were leaders of the Jewish Community Relations Council, the Conference of Presidents, UJA Federation of New York, Board of Rabbis, Anti-Defamation League, American Jewish Committee, the Reform movement, Met Council, Orthodox Union, Agudath Israel of America and Chabad-Lubavitch. Devorah Halberstam and Yaacov Behrman, leaders affiliated with Lubavitch in Crown Heights who recently appeared with Mamdani, did attend.
Some Jewish communal leaders absent from the Gracie Mansion reception have embraced a strategy of total opposition to Mamdani, viewing engagement with him as legitimizing a mayor they see as hostile to Zionism. Other organizations that are dependent on city grants or ongoing access to the municipal government have continued engaging with City Hall even while publicly criticizing the mayor’s rhetoric on Israel and antisemitism.
But that has become increasingly harder for them. The UJA Federation of New York, which hosted Mamdani for a mayoral candidate forum last year, said its leadership did not attend because it was “being hosted by a mayor who denies a core pillar of our heritage — the State of Israel as the homeland of the Jewish people.”
Rabbi Joseph Potasnik, executive vice president of the New York Board of Rabbis, who was among 19 Jewish leaders on Mamdani’s transition team, told the New York Post he declined an invitation to join.
The reception suggested that Mamdani is continuing to cultivate a smaller alternative Jewish coalition, separate from the traditional pro-Israel communal establishment and rooted more in progressive activism and pragmatic community relationships. Mamdani recently appointed Rabbi Miriam Grossman, a JVP activist, as his faith liaison. To his critics, however, the evening underscored how narrow that coalition remains within the broader Jewish community of New York City.
