- 1/2 teaspoon coarse salt
- 1 stick cold unsalted butter, cut into small pieces
- 1 large egg
- 2 to 4 tablespoons ice water
- In a food processor, pulse flour and salt until combined. Add butter and pulse until mixture resembles fine meal, with no large pieces of butter remaining. Add egg and 2 tablespoons ice water, then pulse until well combined and dough holds together when squeezed, 1 minute. If necessary, add up to 2 tablespoons more ice water, 1 tablespoon at a time.
