【How-to】How to line a pan with parchment paper

Q When it says to grease and flour a baking sheet, can I always just use parchment? A The definitive answer is yes and no. Buttering and flouring is one way to be sure cakes won’t stick to the pan. Use parchment, or cheaper wax paper, to line the bottom of the pan, but you should still butter and flour the sides.
