On a recent Thursday afternoon in Brooklyn, six elementary schoolchildren assembled for their Junior Tastemakers class at Creative Cooks, which offers cooking classes for kids from 2-years-old through the 8th grade. In the bright storefront space, a 6-year-old with tousled blond hair named Henry cut a clove of elephant garlic with a large plastic serrated knife. Beside him a brown-haired boy, Alex, also 6, cut a green pepper.
