Fluffy & Flaky Biscuits
2 c. flour
1 T. baking powder
1/2 t. baking soda
1/2 t. salt
1/2 c. butter, frozen
1/2 – 1 c. milk
1. Combine the flour, baking powder, baking soda and salt in a large bowl.
2. Quickly grate the frozen butter on a cheese grater.
3. cut butter into flour mixture.
4. Pour in the milk, starting with just a half cup and adding more as needed until the dough comes together. You want the dough to be soft, but not too soft to handle.
5. Pour the dough onto a well-floured surface and knead for just a minute.
6. Roll the dough into a rectangle. Fold it on top of itself to make 3 or 4 layers. Roll out again and fold into thirds or fourths. Repeat at least one or two more times.
7. For the final rolling of the dough, leave it about an inch thick. Cut out biscuits with a biscuit cutter or glass.
8. Place on a baking sheet and bake at 425 degrees for 8-10 minutes, until lightly golden brown on top. Fold remaining dough back together and roll out again. Repeat process until done.
Makes about 8 biscuits...give or take, depending on how big you make them.
