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.”

Slovenia’s last Jewish institution endures through desecration and decay
On a Saturday morning last July, Robert Baruh Waltl watched two processions converge on central Ljubljana. From one direction, near the river, came a column of neo-Nazis chanting nationalist slogans chanting “Long live Slovenia.” From the other came pro-Palestinian marchers singing “from the river to the sea”.
The city, he notes drily, is very small. “You could see both demonstrations at the same time,” he told me over a video call from his office. “Far right from one side, far left from the other.”
In Slovenia, this is what the view looks like from the only Jewish institution in the country.
The Jewish Cultural Center Ljubljana, which Waltl has directed since its founding in 2013, is overextended by design and necessity. In the absence of a synagogue elsewhere, it functions as one. It is also a cultural center, a museum, and, increasingly, a one-man operation.
“If I’m not in Ljubljana,” Waltl says, “there is no one to even open the door.” For more than a decade, the center has run almost entirely on donations, German embassy micro-grants, and cross-subsidies from Waltl’s adjacent performance space, the Mini Theater. The Slovenian government has never provided stable funding. Applications to the Ministry of Culture go unanswered. “They tell us the Festival of Tolerance is the most important anti-racism event in Slovenia,” Waltl says, speaking of an open event organized by him and the community, “and we don’t receive a single euro for it.”
Waltl did not grow up Jewish. He was born near the Austrian border and moved to Ljubljana as a young man to study theater. Then came a letter from the local Jewish community: did he know that his grandmother had been Jewish? He didn’t. He began attending events, cautiously at first. A trip to Israel changed things. He started reading, learning Hebrew and collecting Judaica. Eventually, he underwent a formal conversion — a giyur — at a liberal congregation in Frankfurt. “I said, OK, now I’m so deep,” he recalls. “I will never feel truly Jewish if I don’t take this last step.”
The community he joined had only barely survived the 20th century. Before the Second World War, Slovenia’s largest Jewish population lived in the Prekmurje region in the northeast. Most were deported to Auschwitz after 1941; roughly 90% were killed. In Ljubljana itself, Jews had been expelled in 1515, and the postwar communist Yugoslav government did nothing to restore their memory: cemeteries and schools were destroyed or simply left to ruin. By the time Waltl arrived, the standard answer when Ljubljana tour guides were asked about Jewish history was blunt: no Jews after 1515. “They didn’t know anything about the Holocaust,” he says. “Nothing about anything.”
His response was methodical. He installed the first memorial plaque on the site of Ljubljana’s medieval synagogue. In 2014, at a gathering of young Jewish leaders in Berlin, he met Gunter Demnig, the German artist behind the Stolpersteine project, and brought the initiative home. Today, Ljubljana and surrounding cities have 68 stumbling stones and one large stone commemorating 150 Jewish refugees expelled from Croatia who sheltered in Ljubljana. He co-founded the Festival of Tolerance with Branko Lustig, the Auschwitz survivor and double Oscar-winning producer of Schindler’s List and Gladiator, born in Osijek, Croatia, who brought early credibility and international reach to the project before his death.
For years, the center also served as a functioning synagogue, anchored by a wave of Israeli tourism. After the Jewish congregation of Slovenia lost its premises in 2014 and moved into Waltl’s building, the arrangement found its footing through sheer numbers. According to Walt 50,000 to 60,000 Israeli tourists visited Slovenia each summer and many of these came to services organized by a Chabad rabbi from Trieste, Ariel Hadad. Then COVID hit. The tourists vanished. So did the rabbi. The pandemic forced a theological rethinking: Waltl discovered liberal Judaism through the Central Synagogue of New York’s online programming and began working with a rabbi from Luxembourg, who now visits several times a year alongside a rabbi from Vienna. When there is money to bring them, they come.
Oct. 7 transformed the center’s situation entirely. On November 6, 2023, someone painted a large swastika equated with a Star of David on the center’s front door. The Jewish graveyard was desecrated during the Festival of Tolerance. When Waltl attempted to screen footage from the Hamas attack for the city’s diplomatic corps, hundreds of pro-Palestinian demonstrators gathered outside and tried to set the doors on fire. The screening was cancelled. There is no Israeli embassy in Slovenia, and no other address for the anger. “In their eyes, we represent Israel,” Waltl says. “We represent everything bad happening in the Middle East.”
Today the center carries a 60,000-euro mortgage taken out for emergency renovations after earthquakes damaged the 500-year-old building, leaving water leaking and unsustainable structural issues. Robert thought that he would receive some sort of financial help from the government to keep this, the only Jewish center in the country, running, but he was unpleasantly surprised to have received none. Since Oct. 7 the relationship with the government soured even more: the prime minister and the president used to show up for Holocaust Remembrance Day and Chanukah festivities, but stopped, says Waltl.
This month, Slovenia changed leadership again, with Israel ally Janez Janša returning as prime minister.
Some other signs of hope: The Rothschild Foundation recently awarded a grant for the country’s first permanent exhibition on Jewish history in Slovenia, set to open this September. The German Embassy contributed 3,000 euros. American tourists — a growing presence — help cover operating costs through summer donations. But the structural problem remains unchanged: roughly 150 Jews, one institution, and a government that adopted the expansive International Holocaust Remembrance Alliance definition of antisemitism, which encompasses anti-Israel actions, while declining to fund the sole organization actually sustaining the community.
“If I say I will stop doing this,” Waltl says, “there will be no Jewish life in Slovenia anymore.”

Volatility, Hit Frequency, and RTP: Why the Number Casinos Advertise Is the Least Useful One
The return to player percentage looks clean as a casino data point. It gives players a neat number, usually around 94% to 97% for many online slots, and that number feels easy to compare. A 96.5% game appears better than a 95.2% game. The problem starts when players treat RTP as a forecast for their next 50 spins or one evening.
You may find the RTP listed on slot pages on a leading online casino in Ontario, but the number only tells part of the story. Two games can share the same RTP and create different sessions: one may return small wins often, while the other may drain a balance before one bonus round changes everything.
The RTP Trap
Return to player (RTP) measures the theoretical share of total wagers a game returns across a very large number of rounds. In plain terms, a 96% RTP slot returns about $96 for every $100 wagered in the long run. That does not mean one player who deposits $100 should expect $96 back.
The trap sits in the word “theoretical.” RTP comes from the game’s math model. It works across huge samples, not personal sessions. A player can finish far above that percentage, far below it, or with nothing left after a short run of poor results.
Is it useless then? No, RTP can still help. It gives a baseline cost of play. Lower-RTP games cost more on average than higher-RTP games. Still, once a game passes a reasonable threshold, the next question matters more: how does it distribute that return?
Hit Frequency: The Number That Shapes Session Feel
Hit frequency tells you how often a game produces a winning outcome. This often misleads players because any win can count. A spin that returns $0.10 on a $1 bet may still count as a hit, even though the player lost $0.90 in real terms.
A game can feel active because symbols connect often, sounds play, and the screen keeps celebrating small returns. The balance may still fall. In many modern slots, “win” does not always mean profit on the spin.
Hit frequency answers one practical question: how much silence can you tolerate? Some players dislike long dry spells. Others accept quieter sessions because they chase bonus rounds or larger payouts.
The educational site Get Gambling Facts gives a useful distinction: RTP concerns the percentage of money returned over time, while hit frequency concerns how often a machine stops on a winning combination.
Volatility: The Risk Label Players Need More Often
Volatility, also called variance, describes how unevenly a game pays. Low-volatility games tend to return smaller amounts more often. High-volatility games hold more value in rare events: bonus rounds, premium symbols, multipliers, or jackpots.
Here is where RTP becomes less useful on its own:
- A 96% low-volatility slot may give modest returns and longer play from the same balance.
- A 96% high-volatility slot may burn through funds quickly unless the player hits a strong feature.
- A progressive jackpot game may look exciting, but it often places more value on rare top prizes.
The same RTP can hide very different risk profiles. Players who ignore volatility often blame the casino or the game when the session follows its math design.
Why the Same RTP Can Feel So Different
Picture two slots with 96% RTP. Slot A pays small wins on many spins, has a modest top prize, and rarely creates dramatic balance swings. Slot B pays less often but offers a large max win and volatile bonus rounds. The advertised return matches, but the experience does not.
Slot A may suit a player who wants a slower bankroll drop and more regular feedback. Slot B suits someone who accepts sharper losses in exchange for a shot at a heavier payout.
A Better Way to Read a Slot Page
Most slot pages give players more clues than they notice. The trick is to read the details together rather than chase the highest percentage.
Start with RTP. If two games look similar, the higher number has better long-term value. Then check volatility. If the game uses terms such as high, very high, or extreme variance, lower your bet size or expect shorter sessions. Next, look at the paytable. A huge max win usually means the game saves a lot of its value for rare outcomes.
A sensible pre-play check looks like this:
- RTP: What is the average long-term return?
- Volatility: How rough can the session become?
- Hit frequency: How often will the game show any wins?
- Paytable: Where does most value sit?
To Conclude
Casinos advertise RTP because it looks objective, tidy, and easy to rank. Players should read it, but they should not give it more authority than it deserves. For long sessions, volatility may matter more than a small RTP difference. For comfort, hit frequency may explain the feel better than the payback rate.

Lahmeyer, pastor who says Antichrist will be Jewish, heads to Oklahoma GOP runoff
(JTA) — Jackson Lahmeyer, a pastor who supports Israel and believes the Antichrist will be Jewish, is headed to a runoff in his district’s Oklahoma congressional primary.
The Donald Trump-backed Lahmeyer will face off against Mark Tedford, a member of the state House of Representatives from Tulsa, in the August runoff to decide who will be the Republican candidate for Congress in Oklahoma’s 1st Congressional District.
The runoff will pit candidates with two very different approaches to politics, and Israel, against each other at a time when the Republican Party is divided on multiple lines. Lahmeyer is part of Trump’s MAGA movement, while Tedford is a more traditional conservative. Both men promote a hard line on immigration, but Lahmeyer’s rhetoric has been peppered with incendiary claims about efforts by Muslims to establish “sharia law” in the United States.
While both competitors are also evangelical Christians with training in ministry, Lahmeyer works as a pastor and preaches an end-times theology that includes an Antichrist with Jewish heritage. Lahmeyer is also a vocal supporter of Israel, in keeping with his Christian Nationalist outlook, while Tedford has made few if any public comments about Israel or the war in Gaza.
The two candidates pulled far ahead of the pack in Tuesday’s crowded primary, which attracted 11 candidates to fill an open seat. Tedford received 32.1% of the votes, and Lahmeyer drew 25.9%, according to the Oklahoma State Election Board.
Lahmeyer had been seen as a favorite, but his star fell in the days before the election amid revelations that he had been unfaithful to his wife. (He said the episode, which he confirmed, was a private matter and in the past, and Trump reaffirmed his endorsement following the revelation.)
Few if any of the nine candidates who did not make the runoff are part of the MAGA movement, suggesting that Tedford could see more of their supporters turn to him in November.
“We need everyone who came out today to keep fighting until we succeed,” Lahmeyer said in a statement to local media. “Let’s send a Trump-endorsed warrior to fight for Oklahoma values in Congress.”
The district is solidly red, virtually assuring the primary winner of victory in November. The Democratic candidate, John Croisant, is a Tulsa school board member who has not spoken publicly about Israel or Gaza, issues that are occupying some Democrats.
