In a food processor, add flour, salt, and sugar. Pulse a few times to incorporate.
Add in butter and Star Fine Foods’ Agrenna. Pulse until the mixture resembles coarse peas. With the food processor still running add the water-vinegar mixture one tablespoon at a time until the dough begins to form a ball.
Dump the dough out onto a floured surface and divide it in half. Shape each piece into two balls and flatten. Wrap with plastic and transfer to the fridge for at least 2 hours.
Use this pie dough as instructed by any pie recipe.
