To Thrift or Not to Thrift: Bake that rust right into that cake!
The next recipe instruction could be: Bake 45 minutes, let cool, and discover myself shaving rusty crusts off my delicious-sounding ginger pound cake. Cupcakes look lovely, until you follow the recipe for your favorite corn muffins (which calls for baking them without liners) and I discover the discoloration is not due to the authentic stone-ground cornmeal I'm using.
I'm pretty sure that the doctor did not order up a dose of various oxidized metals with your home-baked goodies. Don't eat your metal when you don't want to. Buy baking tins brand-new.
