Pastry Chef Chika Tillman, the chick with a whisk, gives diners a voyeuristic thrill as she preps, pipes and plates her desserts in expert fashion. A multicourse “meal” may include an amuse-bouche such as coconut sorbet in a little pool of chocolate-infused tea gelée. The main course might be a warm chocolate tart with pink-peppercorn ice cream, a mocha-and-hazelnut trifle or a delicious fromage blanc cheesecake. It all ends with darling petit fours. As if you needed them.
