I made this but crustless last night. It actually firmed up enough to be served as a pie without the crust! In place of the pumpkin,sugar and spices, I used one can of pumpkin pie filling. I'm sure that it had less than 1 cup of sugar in it and it was still sweet enough (some might say not enough, depends on your sweet tooth.) One may want to add the sugar in increments while tasting instead of just dumping in one whole cup. If it were up to me I would stick to using the pie mix but maybe adding some more of the spices... hubby on the other hand liked it better with less spice. The reason it was not 5 stars is that the milk is missed... there is a slight soy underflavor. Perhaps we could reduce the amount of tofu? I used one 12oz carton of silken tofu.
