Help! I just moved into a new apartment with an oven that has four options: convection cooking, convection broiling, broiling, and defrost(??). I tried baking a sponge cake for tres leches last night, and while it rose hugely and browned nicely, it fell within a few minutes of being taken out of the oven. Now I'm reading in various places online that convection ovens are actually lousy for cake baking...but given my lack of ability to switch to a conventional mode, is there any other way I can adjust the baking process to improve my results? TIA!
