crust several times with a fork to keep the crust from puffing up during the baking. Place the springform pan in the oven and bake for 15 to 20 minutes, or until light brown. Allow to cool. Using the leftover dough, line the sides of the springform pan. Press the dough against the sides of the pan, smoothing it so as to have a continuous layer of crust all the way around the sides of the pan. Make sure that the side crust meets the bottom crust all the way around. Brush the reserved egg white onto the shell, covering the bottom and sides. This will seal the dough and keep it from becoming soggy. Set aside until ready to use. NOTE: For the Italian Cheesecake, add 1 ts of grated lemon rind and 1 ts of Amaretto Liqueur when adding the egg yolk and butter. ----
