It takes about 9 full graham crackers to crush into the 1 ½ cups. With the sugar, you may mix in spices for additional flavor. For a regular cheesecake, vanilla pie or banana pie, a tsp of cinnamon; for an apple pie type of filling, use ½ tsp cinnamon and ½ tsp nutmeg. You could even mix in some small chocolate chips or chocolate shavings for a chocolate pie. For tips on making the egg yolk brushing a bit easier, see the post. For a very quick pie, make your favorite pudding and just fill in the crust. I know it sounds really basic, but chocolate pudding in a graham crust is delicious.
