HiyaI wouldn't use margarine on a bet for anything. I use only unsalted butter. I don't like anything fake, like Krab, margarine, the parmesan stuff in the can. Gotta be the real thing, it does make all the difference in the world to me. And I CAN believe it's not butter. AAAACCCCKK. Are they kidding? Stick with butter. Sorry for the pun.
P. S. The butter bell is one of my most valuable "gadgets."
It's okay to use margarine to grease cake pans, but little else. Butter leeches water when it melts at cake baking temp, making your grease/flour mixture at the bottom of your cake pans steam. Margarine, on the other hand, won't steam the bottom of the cake.
