Chef John's Butter Puff Biscuit Dough
You can make your own self-rising flour by sifting together 2 cups of all-purpose flour with 1 tablespoon baking powder and 1 teaspoon fine salt.
After you have grated the frozen stick of butter for the first layer, place it back into the freezer for the second grating.
I generally bake this dough at 400 degrees F (200 degrees C). Time will depend on what it's being used for.
