Chef Sandy (Stollar) Leibowitz is a South American Jew who trained at the Culinary Institute of America (CIA) and sharpened her knives at some great non-kosher restaurants in New York City (the Russian Tea Room, Osteria Del Circo, Oceana, Spice Market, etc.)
After working at the only kosher kitchen - Levana, she started her own Chef Service company called The Kosher Tomato, which serves the kosher style or super strict. She writes a (semi) weekly blog on her site. She also taught cooking classes at the Center for Kosher Culinary Arts in Brooklyn. Leibowitz, who was featured in the “Heeb 100,” in 2009 (Under maiden name "Stollar") is undoubtedly one to watch in the coming years.
