Making your own pie crust is not very difficult and worth the effort. I no longer use butter, but have found that a mix of Earth Balance Vegan Butter and Earth Balance Shortening works just as well. Here’s a recipe for a basic pie crust.
Whisk the flour, sugar and salt until well combined.
Cut in the shortening and vegan butter. You can cube it before hand to make it easier to incorporate. A pastry blender or two butter knives work well. Cut in the fat until the flour mixture resembles cornmeal, with small bits of fat showing.
Combine the ice water and vinegar.
Drizzle 1/3 of it over the flour mixture and stir with a fork. Continue with the remaining liquid or until the dough forms a soft ball when pressed together. If it is still too dry add a tablespoon of ice water at a time until it can be gathered into a ball.
