NEW YORK, May 13 (JTA) — "It started with a mistake," says chef Jeffrey Nathan, explaining how he created his Smoked Salmon Cheesecake recipe. "I added salt instead of sugar to a cheesecake batter." Instead of dumping it into the trash, he turned the traditional Shavuot dessert into a savory appetizer. "Actually, the inspiration came from Emeril Lagasse," he says, referring to the Food Network chef. "I saw him preparing something similar with crayfish and sausage — very treif foods. Whenever I see unkosher dishes, I look at them and figure out what ingredients can be substituted to make them kosher." Influenced by everything from Latin American to Asian and Mediterranean cuisines, Nathan tweaks Jewish recipes, often turning them inside out. But he always presents sophisticated, flavorful fare that is visually appealing. Since 1998, Nathan has been the host chef of public television’s New Jewish Cuisine, the only national kosher gourmet cooking series. His first cookbook, "Adventures in Jewish Cooking," is a collection of exciting kosher recipes that reflect his playful approach to flavor combinations that yield seriously delicious results. Nathan is also the chef at Abigael’s on Broadway, an upscale kosher restaurant in midtown Manhattan. So how did a Jewish boy from Queens change the course of kosher cuisine? "Believe me, I was the perfect example of a guy who thought that Jewish cooking meant a pastrami sandwich on rye or a bagel with a schmear," Nathan says in his book. "In our household when I grew up, Jewish cooking was personified by my family’s recipes for matzo ball soup, stuffed cabbage, and blintzes." Since then Nathan has traveled a long way, but in some sense, he’s come full circle. "My professional career began as a dishwasher at Villa Russo, an Italian restaurant," Nathan says. "There, despite the piles of dirty pots and pans, I discovered a passion for cooking." He joined the U.S. Navy as a cook, and Uncle Sam paid for his first round of travel, an opportunity he used to try exotic seasonings and collect recipes. Becoming the personal chef to the captain and officers, he shopped at local markets in different ports of call. He began experimenting with upscale recipes. After four years at sea, he enrolled in the CIA — the Culinary Institute of America in Hyde Park, New York. Nathan earned his mettle, or rather his skill with cast-iron pots, in the kitchens of famed Manhattan restaurants, such as Luchow’s, The Company and New Deal. In 1996, after two decades in the business, he bought Abigael’s. Most people thought he’d lost his mind. "I was already an established chef with a reputation," Nathan says. "My friends asked me: At this stage of your career, why go into kosher foods?" But while they were thinking of brisket and borscht, he was thinking of introducing Jewish cooking to contemporary cuisine. "I didn’t want to serve the same old dishes that everyone expected, but an updated fresh version of kosher cooking. At Abigael’s, I began to put some Sephardic dishes on the menu, exposing many of my clients to this spicy, exciting cuisine for the first time." His concept was to use a light touch to develop elegant dishes. He explored culinary delights from the entire Jewish Diaspora. Breaking stereotypes, he revolutionized the menu at Abigael’s, which now features a palate of colorful foods from Italy to the Pacific Rim, from Japanese sushi, to French and Vietnamese cuisine. "Nuanced is how I describe my cooking," Nathan says. "I don’t like something that is just sweet or spicy. I like foods that are opposites. Both crunchy and creamy, like Creme Brulee." Although Creme Brulee, like Tarte Tatin and Tiramisu, came of age since Nathan’s youth, all three desserts are excellent choices on Shavuot, an often overlooked but significant holiday on the Jewish calendar known for its dairy connection. Shavuot commemorates the giving of the Torah to the Israelites. Historians speculate that they abstained from meat at this pivotal moment in history. Some pious Jews compare the purity of the Torah to the whiteness of milk. "When I was growing up, I liked Shavuot because we consumed dairy like crazy," Nathan says. "It was a morning holiday, full of brunch foods." Like many Ashkenazi Jews, the Nathans ate the standard kugels and cheesecakes. But now that he is the maven of nouvelle Jewish cuisine, what would chef Nathan suggest serving this Shavuot? Besides his Smoked Salmon Cheesecake, which is not only sensational when spread on crackers or black bread, but also makes a splash on a buffet table, Nathan mentions other enticing recipes. "My kids love their dad’s version of Tex-Mex mac and cheese," he says explaining that his son, 15, and daughter, 12, adore this Spicey Macaroni Kugel with Three Peppers. They help him prepare it by chopping and cooking ingredients. It’s a wonderful way to bring the whole family together. Like so many great culinary discoveries, this dish also started as a misstep. "I made it too spicy at first," he says. "I like to play around with peppers. But if your family is chili challenged, you can leave out the jalapeno and still have one terrific dish." His Beet, Pear and Fennel Salad is an elegant and colorful addition to the menu. Its pungent sweet and sour orange vinaigrette cuts the richness of dairy. "I prefer not to boil the beets because baking intensifies their sweetness," Nathan says. "When you boil beets, the flavor leaches out. You throw away the color with their amazing taste." Of course, Nathan’s signature dish, the one that keeps customers flocking to Abigael’s, is his Chocolate Mousse Flowerpots, which he developed in a lighthearted way. He went to Home Depot to buy a friend a housewarming gift. He selected a clay pot. Bringing it home, he filled the pot with chocolate mousse and covered it with chopped cookies that looked like "dirt." He poked a couple of flowers into his creation. "While everyone else came with housewarming gifts, I placed the flowerpot on the center of the table." The host and guests had no clue what was really inside. We had dinner and after it was over, I spooned some of the flowerpot contents onto my plate and started eating it. Everyone looked confused and distressed. "Did he have too much to drink?" they whispered. But once he told them the centerpiece was a dessert, the chocolate mousse was a big hit. Today people who are kosher follow food trends like everyone else. They want the same culinary experiences that other Americans enjoy. They want access to Mexican, Japanese, Vietnamese, Thai, Greek, Italian, and Middle Eastern cuisines. Thanks to Jeffrey Nathan, there’s no reason why they can’t have the best of both worlds. "When I bought Abigael’s, people told me that brisket and matzo ball soup are so yesterday," he says. "But I decided that kosher food doesn’t have to be so stereotyped. It can be anything as long as it conforms to the laws of kashrut." "My exploration of modern Jewish cooking was the beginning of a new chapter in my development as a chef — and as a person. Over the years, I admit that I had jumped around a bit, getting recognition as a wild game chef, and even as an Italian cook. But Abigael’s was my bashert — it’s where I was destined to find myself. As I honed the recipes for Abigael’s menu, I realized that I had come home, both spiritually and professionally." In the same way that the Children of Israel received the Torah from God, Shavuot is a time to look forward and back, to honor tradition but, like Jeffrey Nathan, also to shake things up a bit.SMOKED SALMON CHEESECAKE2 Tbsp. unsalted butter, melted3 Tbsp. freshly grated Parmesan cheese3 Tbsp. seasoned dried breadcrumbs2 Tbsp. vegetable oil1/3 cup finely chopped onion1/3 cup finely chopped red bell pepper1/3 cup finely chopped green bell pepper1 tsp. kosher salt1/2 tsp. freshly ground black pepper11/2 lbs. cream cheese, at room temperature4 large eggs, at room temperature8 oz. sliced smoked salmon, chopped2 Tbsp. chopped fresh dill1/2 cup shredded havarti cheese1/3 cup heavy cream1.
