For extra golden tops, brush biscuits with buttermilk before baking.
To keep the butter cold, refrigerate the dough briefly if your kitchen is warm.
Leftover biscuits can be stored in an airtight container for up to 2 days at room temperature or up to 1 week in the fridge.
Reheat biscuits in a 350°F oven for 5-7 minutes or microwave with a damp paper towel for 10-15 seconds.
