I love the fact that the recipes I am posting from my Mom's recipe box show their age. These recipes were before the invention of ready made pie crusts :-) Thank goodness for modern technology!!! I do not have too much luck with homemade pie crust.
Take your fresh sweet potatoes and boil them until tender. Remove the skin and mash them. Measure 2 cups. Place in a bowl. Using a mixer, beat egg yolks into the mashed sweet potatoes. Add butter, sugar, milk, salt, and lemon rind. Mix well. Pour into the pie crust and bake at 350* for 30 minutes or until set.
