This is a heavily modified version of my grandmothers' recipe that I've made vegetarian and dairy free. She made it every Thanksgiving. We never had the regular kind and there is no substitution for this amazing pie. I have made this healthier than the original but I will post their original recipe as well. You cannot tell the difference! Try it with a gingersnap or pecan crust. I usually add a 1/2 tsp. of vanilla but it's not necessary. I use soy milk but you can use almond milk, oat milk or dairy milk. Wonderful with a little fresh whipped cream but really doesn't need a thing. This is also good for Christmas.
