Freeze the stick of butter. Chill the measured flour and buttermilk.
Grate the buttter, tossing it with the flour a little at a time.
Stir in the buttermilk just until the ingredients are blended. If dough feels dry 1-2 Tablespoons additional buttermilk can be stirred in.
Place dough on a lightly floured surface and pat down to about ½ inch thickness. Fold in half and pat to ½ inch again. Repeat the fold and pat down step 4 times.
Roll with a rolling pin or pat down with hands until about ½ inch thick.
Cut with a biscuit cutter using a straight down and up motion (do not twist). Place biscuits on parchment lined baking sheet nearly touching.
Bake at 450 degrees 12-14 minutes or until lightly browned. Brush with melted butter if desired.

Notes
Using a 2 and ½ inch biscuit cutter will yield approximately 12 biscuits. You can cut biscuits once and then re-roll the dough and cut again to get the most biscuits from the dough.
Salted or unsalted butter may be used.
Check the recipe post for substitutions for self rising flour and buttermilk.
