Kaul attended the celebrated French Culinary Institute in Manhattan and, upon graduation, entered the fiercely competitive world of top-flight New York restaurants. After working her way through the ranks at Union Square Cafe, she went on to assume the prestigious saucier position at Lespinasse, eventually leaving to become a sous-chef at Gramercy Tavern. As Kaul's reputation grew, she came to the attention of Bob Spiegel and, in the fall of 1996, was enlisted as chef for Bob's new venture, Daily Soup.
