Pureed pumpkin is wetter than canned, but I never have a problem substituting 2 cup of fresh for one small (15 oz) can. With 2 eggs my pies always set OK. And, instead of half-and-half or cream plus brown sugar, I use 1 can of sweetened condensed milk. So my filling has only 4 ingredients, the fourth being pumpkin pie spice.
Jeff does a great job portraying Mamet as the most self-centered, self-absorbed character I’ve ever seen in a comic strip, except maybe Rat.
