Morrison's Cafeteria Recipe
11 ounces sugar
4 ounces dried powered milk
1 1/4 ounces tapioca flour
3 1/2 ounces margarine at room temperature
6 large eggs
1/4 teaspoon pure vanilla extract
1 quart ice water
2 pastry shells
Sift into a large bowl of mixer the sugar, powdered milk and tapioca flour. Blend together just to incorporate dry ingredients. Add the margarine and mix on medium speed for two to three minutes.
Add half the eggs and whip on high speed for one minute. Stop mixer and scrape down the sides of bowl with a spatula. Add remainder of eggs and extract and mix for one more minute on high speed.
With machine on low, add ice water and allow to mix smoothly. Pour into two pastry shells and fill to the top. Break air bubbles on top to prevent spots on the pie. Bake in 375 degree oven for 30 to 35 minutes.
