i'm making a gooey pumpkin butter cake and a pear cake, both which require square baking dishes, so i need to go buy some tonight. which kind are best? glass, aluminum, ceramic, etc.? should i just go to target and get the inexpensive pyrex dishes, or spend more and get an emile henry or le creuset at sur la table? ideally, i'd like one that's most versatile to be used for desserts and casseroles alike in the future. thanks!
