We usually spend our Saturday afternoons doing the errands we’ve avoided during the week: cleaning the apartment, filling our fridge, nursing a Champagne-induced hangover (okay, maybe that one should be relegated to Saturdays only). But once we have a spotless kitchen and packed cabinets, we’re not exactly sure what to do with them. So we’ve penciled the Celebrity Chefs Culinary Program at the Fairmont Copley Plaza (138 St. James Avenue, Boston, 617.267.5300) into our calendar. The series includes weekly two-hour cooking classes with local chefs, plus the chance to eat your homework and sip cocktails while doing it. To sign up for the January 17 course with Petit Robert Bistro’s Jacky Robert or the January 24 “Taste of New England” lesson with the Fairmont Copley’s Laurent Poulain, call the Boston Center for Adult Education at 617.267.4430. All classes begin at 1 p.m. and are $60.
