It wasn’t until January 2000 that Delphin Gomes, whose instructional credentials include Boston University, Cambridge Culinary School and UCLA, decided to open a pastry school. He now teaches dilettantes and pastry professionals alike the tricks of the trade as he knows them. Take a look at some of his most photogenic creations or at a list of upcoming classes.
