Attention, foodies: The Food for Thought Stage presents a Sustainable Seafood Panel with James Beard Award-winning chef Spike Gjerde, Gertrude's at the BMA owner John Shields and owner of the True Chesapeake Oyster Co. Patrick Hudson. The panel concludes with an oyster shucking demonstration and tasting. 3:30 p.m. Saturday. And at noon Sunday, Allison and Matt Robicelli — who are bringing their famed bakery to Baltimore — will discuss their new cookbook, "Robicelli's: A Love Story, with Cupcakes: With 50 Decidedly Grown-Up Recipes." It features confections flavored with such decidedly grown-up ingredients as figs, whiskey and fried chicken.
