Otter, try these - they're TNT from my grand MIL in NC -
½ cup butter
2 cups self-rising flour
3/4 to 1 cup buttermilk
Preheat oven to 425; grease a baking sheet or use a sheet of parchment paper.
Cut in butter and flour coarsely. Add milk, stir to just incorporate. Turn out on floured board, knead 3-4 times. Pat dough out to a rectangle 3/4 inch thick. Cut out biscuits, place on baking sheet. Dip your knuckles into a small dish of buttermilk, and lightly indent the biscuits. Bake 13-15 minutes, til light brown.
To make drop biscuits, increase milk to 1 ¼ cups and drop biscuits on baking sheet.
I never roll out my biscuit dough - I just pat it out on a floured board - and instead of using a round cutter, it's a lot easier to just take a knife and cut out squares - that way, you don't have to reroll and cut the scraps.
