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.”

Stabbing of Jewish man in Manhattan prompts calls for Mamdani to turn down temperature
The stabbing of two men on Manhattan’s Upper West Side on Thursday — one of whom was wearing a kippah on his way home from a Tisha B’Av service at a modern Orthodox shul — has intensified New Yorkers’ fears of being visibly Jewish in public, leaders and community members said.
“Fear has become a lived experience for far too many Jewish New Yorkers. That is not normal,” Mark Treyger, CEO of the Jewish Community Relations Council, said at a press conference Friday near the location of the stabbing. “Today, Jewish parents are asking whether it is safe for their children to wear a kippah or a Magen David in public. Synagogues preparing for Shabbat are wondering whether they can afford additional security.”
Police said on Thursday afternoon, the suspect — identified as 51-year-old Raul Morales — stabbed an Asian man in the back with a knife before approaching a Jewish man and stabbing him in the torso with a screwdriver. Authorities said he yelled “Allahu akbar” during the attack. Both victims are expected to recover.
Morales is expected to face charges on Friday. Police are investigating the attack as a hate crime, and New York City Police Commissioner Jessica Tisch said in a statement Thursday that while the attacker did not have a known history of mental health issues, “the initial investigation suggests that mental health may have been a factor.”
New York Mayor Zohran Mamdani condemned the attack as “horrifying” and wrote on X that “these hateful and despicable attacks have no place in our city.”
At Friday’s press conference, City Council Speaker Julie Menin said she was having conversations with her daughter about whether it was safe to wear a Jewish star and with her sons about whether they should wear yarmulkes.
“How can this be normal?” Menin said. “We have to change what is happening in our city.”
But even as New York Attorney General Letitia James urged people not to “assign any particular outcome to this investigation,” adding she did not want to “draw any conclusions,” some leaders were quick to link the attack to a rising political temperature.
Some directly expressed their anger with Mayor Zohran Mamdani, who on Wednesday issued a video address conceding he did not have the authority to arrest Israeli Prime Minister Benjamin Netanyahu, while also calling Netanyahu a war criminal and accusing him of orchestrating a genocide. Unable to arrest Netanyahu, Mamdani encouraged New Yorkers to protest instead.
The UJA-Federation of New York and Orthodox Union said at the time that the mayor’s words put Jews in greater danger.
Rabbi Angela Buchdahl, the spiritual leader of Manhattan’s Central Synagogue, wrote in an open letter addressed to Mamdani that “you promised during and after your campaign to lead this city with unity rather than fear. Instead, you continue to divide Jews into those whose politics you deem acceptable and Zionists whom you cast beyond the pale.”
Mamdani was not at the press conference, and organizers did not answer a question about whether he had been invited.
“His words have profound, real-world consequence on us,” Eric Goldstein, CEO of UJA-Federation of New York, told the crowd. “Shame on him for doing this for perceived political benefit when it has real-world consequence for the Jews of New York. He must stop. He must stop.”
Rabbi Yosie Levine of the Jewish Center — where the victim had attended a Tisha B’Av service before he was stabbed — also expressed disappointment at Mamdani’s remarks.
“When I was growing up, the only time we saw security outside of my synagogue or outside of my Jewish day school was when the mayor came to speak,” Levine said. “The police were there to protect him. Today, every time the mayor speaks, we need the police to protect us.”
“No elected official is responsible for every act of hate, but every leader is responsible for helping shape the climate in which we all live,” Treyger said.
New York City Comptroller Mark Levine at Friday’s press conference cast the attack as part of a broader trend of rising attacks on Jewish New Yorkers, citing 178 acts of antisemitic hate crimes in the first six months of this year.
Menin pointed to the dozens of swastikas painted on a playground at a Brooklyn playground earlier this year and swastikas spray painted on homes and a synagogue in Queens last month. On Wednesday, a Jewish man was shoved to the ground in Brooklyn, with the attacker making antisemitic remarks, leaving the victim with back and hip injuries.
Thursday’s attacks were just the latest in a series of crimes targeting the Jewish community, they said.
Rabbi Mark Wildes of the Manhattan Jewish Experience told the Forward he was teaching his weekly class when the attacks occurred nearby.
“It literally happened on my block,” he said. “Two of my kids were out and about, and this guy was still at large before they had caught him.” Wildes, whose children are visibly Jewish, said he and his wife immediately tried to get them home. “We were saying, ‘Where are they? Get them inside.’”

Assailant stabs two men, one visibly Jewish, on Upper West Side
(JTA) — NEW YORK – An assailant stabbed two victims, at least one of whom was visibly Jewish, in an area of the Upper West Side known for its Jewish institutions.
Police said two male victims, aged 57 and 50, were in stable condition and being treated for stab wounds to the torso.
Rabbi Allen Schwartz of the neighborhood’s Congregation Ohab Tzedek told the Jewish Telegraphic Agency that one of the victims was a congregant who is visibly Jewish and wears a kippah.
Schwartz, who is in Israel, said he spoke to the congregant on the phone and that he is “alert.” “He may go home before Shabbos,” Schwartz said.
One person of interest has been taken into custody, according to the New York Police Department, who announced no immediate motive for the attack.

What sort of Yiddish do Yiddishists speak today?
Ask the question: “What sort of Yiddish do Yiddishists speak?” and a jokester might respond: “Well, these days they speak English.”
But let’s consider the Yiddishists who really do speak it in order to preserve it as a living language, because they see it as a treasured part of the Ashkenazi cultural heritage.
Their purpose is different than the Hasidim who speak the language as a way of preserving their religious lifestyle and traditional Jewish values.
Linguist Emma Breslow recently defended her dissertation about the way that Yiddishists speak the language. She interviewed 30 Yiddish speakers at the annual week-long Yiddish immersion retreat Yiddish Vokh and also met with Yiddish speakers from New York, Boston and Montreal.
When she asked people whether they considered themselves Yiddishists, most said no. Perhaps the words Yiddishism and Yiddishist sound rather old-fashioned today. Since Breslow couldn’t find a label that speakers could agree on, she uses the phrase “minority-context Yiddish community” in her study. This category, she writes, also includes former Hasidim who occasionally participate in Yiddishist gatherings.
One surprise in her dissertation is the diversity in this community’s Yiddish. An outsider might assume that all Yiddishists speak the same but that isn’t so: some adhere to Standard Yiddish — the literary standard established by the YIVO Institute for Jewish Research and used in most Yiddish language courses today. Others use the Polish or Ukrainian Yiddish dialect or switch dialects. Sometimes they would say gut (good) and other times — git; sometimes zogn (to say) and other times — zugn.
When Breslow asked people their opinion of Standard Yiddish she mainly received negative answers, although some acknowledged that Standard Yiddish could be useful for learning the language, since the spelling closely matches the pronunciation.
Some interviewees made unexpected comments about Standard Yiddish, as in “Nobody speaks that,” even if, being at the Yiddish Vokh, they might have earlier chatted with Standard Yiddish speakers, and even heard children speak it as a native language. Her dissertation discusses this feeling they have that Standard Yiddish lacks authenticity — maybe precisely because so few people speak it from birth.
The minority-context Yiddish community consists of several groups: a) native speakers — those who speak Yiddish well from home; b) heritage speakers — those who heard it as children, but don’t speak it well; c) students and others who studied the language as adults, and d) former Hasidim, who now live in the larger secular world. Each group speaks differently, but there are interesting points of comparison.
Among her subjects, the former Hasidim speak so-called Hasidic Yiddish — a dialect that linguists have been researching intensely in recent years. Students mostly speak a sort of Standard Yiddish, which they learned from their teachers. All of the Yiddish speakers often exhibited a certain influence or interference from English; no surprise, considering that Hasidim — the largest group of Yiddish speakers today by far — mix English words into their Yiddish too.
Breslow’s quotations include interesting examples of code-switching — when speakers go back and forth between languages. Some of the younger speakers use the word like as a discourse marker in their Yiddish just as in their English.
A second topic of Breslow’s investigation is the articulation of the Yiddish letter reysh, which is similar to the R sound. In the older dialects there were two sorts of reysh: the throat (uvular) reysh, like in French or Modern Hebrew, and the tongue-tip (apical) reysh, as in Russian or Spanish. In addition to those two pronunciations, today’s Yiddishists also use the English-style (retroflex) reysh. Interestingly, linguist Uriel Weinreich, who authored the textbook, cautioned in the preface that students should not use the American reysh.
The grammar of the Yiddishists is also worth examining. Although many have taken courses teaching the grammar of Standard Yiddish, they don’t necessarily follow the rules. That shouldn’t come as a surprise, since even authentic Yiddish speakers of previous generations spoke in dialects that differed considerably from the way Yiddish was written in books and in the press. That’s why there’s no reason to criticize Hasidim for “ruining the grammar,” as many non-Hasidic Yiddish speakers do, since Yiddish speakers have been “ruining” the proper grammar for centuries.
