Note: To make a parchment round, cut a piece of parchment at least as long and wide as the pan. Fold in half, then again to quarter. Then turn and fold in half diagonally, centering the fold on one of the corners. Repeat twice more so that you end up with a narrow triangle. Measure 4 1/2 inches from the point and cut away the loose ends with scissors. When you unfold, you should have a near-perfect 9" diameter parchment circle. If you don't, I wrote something wrong. Oh, and make another one for the top while you're at it.
