At Jezebel, the Cocktails Must Be Kosher Of all the mixologists charged this year with creating a cocktail list in New York, Nick Mautone, the beverage director at the new SoHo restaurant Jezebel, may have faced the greatest challenge. Jezebel is a kosher restaurant, and the cocktails also had to fall in line with the laws of kashrut. Kosher wine lists are common in New York, and relatively easy to assemble. All a wine director has to do is look at the label. If it has a hechsher (a symbol of kosher certification), the bottle is a potential candidate for the cut. If not, it's not. But cocktails are composed of a panoply of ingredients, every one of which must be checked out. Base spirits are the easy part. "Most spirits are kosher by definition because they're distilled," Mr. Mautone said. All the impurities have been removed. The majority of vodkas, gins, whiskey and tequilas are all kosher. Still, you have to keep your eyes peeled. Some flavored vodkas and whiskeys are not eligible. And many whiskeys today are finished in wine barrels (port, sherry), a technique that negates their kosher bona fides, since all wine products must be certified. But a glass of whiskey is not a cocktail. It requires modifying agents, and that's where things gets hard. Many of the famous liqueurs and bitters - Campari, Benedictine, Chartreuse, Dubonnet, Peychaud's bitters - that are required to make some of the world's most famous cocktails are not kosher. That means no Negronis, no Sazeracs, no Vieux Carres, no Bobby Burnses. It's enough to break your heart. It gets worse. Owing to its wine base (not to mention the usually secret mix of informing herbs and spices), all of the major brands of vermouth are out of the game. The only kosher dry and sweet vermouths on the market are made by Kedem. And that doesn't suit Mr. Mautone. "Kedem vermouth is not bad," he said, "but when you're used to Noilly Prat or Carpano Antico, it's not good enough." Life at Jezebel without martinis and manhattans is too grim a prospect to contemplate, so Mr. Mautone is planning house-made vermouths. "Once the ingredients come in and are approved," he said, "and I have a distilled spirit that's approved, it's kosher." Thank goodness that Angostura bitters, essential to completing a manhattan and so many other cocktails, have long been kosher-certified. In the meantime, Jezebel is introducing a 6-drink list, which Mr. Mautone plans to expand to 20 in a few weeks. Each drink shows a bit of necessity-is-the-mother-of-invention creativity. The Kosha Nostra, a vodka cocktail, finds its orange-chocolate accent in Sabra, a Kosher Israeli liqueur. Jezebel's Singapore sling keeps the gin and Cherry Heering that are common parts of this classic cocktail, but leaves their frequent companion, Benedictine, on the shelf. And the rum-based Aaron's Staff draws flavor from both the kosher-certified Disaronno, a spiced syrup of clove, star anise and allspice, and almond milk. The almond milk is a sly biblical reference. In the book of Numbers, Aaron's staff magically spouts, producing ripe almonds. "Most people wouldn't get that," Mr. Mautone said.
