Greasing Muffin Tins
The trick to preventing muffins from sticking to the muffin tins is to grease each muffin cup thoroughly. First, melt a small amount of butter in a saucepan over low heat. After the butter is melted, remove from heat. Dip a pastry brush into the butter and use it to lightly coat each muffin cup, making sure you get the bottom, sides, and corners of the cup.
