First, open a nice dark beer for yourself. You'll need a bit of it for the recipe, and you might as well be sipping until that point.
½ cup butter
½ cup sharp cheese, grated
1 cup flour
Pinch of powdered mustard
A tiny bit of beer to moisten the dough, if needed
Blend, form into a 12 inch roll, chill, slice; or roll into small walnut-sized balls and flatten on an ungreased cookie sheet. Bake at 350 for 20 minutes.
These make a nice appetizer to have along with drinks. Makes about 36 little biscuits.
