Test Kitchen's Favorite Buttermilk Biscuits
Biscuits can be formed, loosely covered, and stored in the fridge the night before. Brush the tops with buttermilk just before baking.

For even taller biscuits, trim a scant 1/4 inch from the 4 sides of the dough before cutting into thirds. This exposes the layers after folding and ensures that the biscuits grow in the oven as much as possible.
