Sift the flour and salt into a large bowl. Cut in the shortening and the butter to the dry ingredients until the flour mixture resembles coarse crumbs. 3 cups all-purpose flour, 1/2 teaspoon salt, 1/2 cup shortening, 1/2 cup cold unsalted butter
Mix the water and vinegar together in a cup. Add the mixture to the crumbs. Mix together just until the dough is combined and handles well. 1/2 cup ice cold water, 1 tablespoon white vinegar
Sprinkle flour on the counter before rolling out the dough. Split the dough into two discs. Roll out one disc on a floured surface to between 1/8-1/4" thick. Use cookie cutters to cut shapes. Then repeat with the other disc and re-roll any scraps.
Place cookies on a parchment paper lined baking sheet. Sprinkle the tops with sugar and cinnamon, if desired. granulated sugar and cinnamon
Bake for 10-12 minutes, depending on how big the cookies are and how thick they are. I don't let them get browned, which will ensure they are soft.
Notes
The amount of cookies you'll get depends on the size of the cookies you cut and the thickness of the dough. I got about 24 medium size pie crust cookies.To make the cookies golden brown on top, use a pastry brush and lightly brush the top of the cookies with egg wash or heavy cream before baking. Sprinkle the tops with sugar and the wash will help it stick!Store the cookies in an airtight container at room temperature. The cookies also freeze well for up to 6 weeks.Refer to the article above for more tips and tricks.The calories shown are based on the recipe making 24 cookies, with 1 serving being 1 cookie.
