This is probably a stupid question, but I don't bake much, and a search didn't yield any helpful results.
I have a recipe for a cake that says "butter and line a 9 inch springform pan." Does this mean butter the pan, then line the pan with parchment paper? If so, why do I need the butter - just to help hold the paper in place? I have seen recipes that say to butter and flour a pan, or line a pan (often just the bottom) but I haven't seen them together before. (And I've never used one with paper in a springform pan, but like I said - I don't have much experience baking.) To me, it seems like the paper would be enough to keep it from sticking, so I don't understand the buttering.
Thanks in advance!
