Frozen mini pie crusts contain enriched wheat flour, which is made up of wheat flour, niacin, iron, thiamine mononitrate, riboflavin, and folic acid, partially hydrogenated lard with BHA and BHT to protect the flavor, water and sugar. The pie crust also contains 2 percent or less of whey, salt, baking soda, sodium metabisulfite (which is a preservative), yellow 5, yellow 6 and a trivial amount of trans fat from the dyes.
Frozen mini pie crusts contain wheat and milk produces, which may cause allergies in certain people to act up. The recommended serving size for one of the frozen mini pie crusts is one eighth of a crust, or 21 grams. These facts and ingredients can alter depending on the specific brand of pie crust purchased. The crusts, when purchased in the frozen form, come in two main types, either lard shortening based or vegetable shortening based. Vegetable shortening crusts do not contain cholesterol, which is more ideal for health conscious buyers. However, the lard crust makes for a flakier shell, which is preferred flavor wise and can handle heavier ingredients like meringue and cream. Both pie crust bases do provide a time-saving and efficient way to make up a pie, however.
