Preheat your oven to 450 degrees F.
Combine the dry ingredients in a bowl, or in the bowl of a food processor.
Cut the butter into chunks and cut into the flour until it resembles course meal.
If using a food processor, just pulse a few times until this consistency is achieved.
Add the buttermilk and mix JUST until combined.
If it appears on the dry side, add a bit more buttermilk.
Turn the dough out onto a floured board.
Gently, gently PAT (do NOT roll with a rolling pin) the dough out until it's about 1/2" thick.
Use a round cutter to cut into rounds.
You can gently knead the scraps together and make a few more, but they will not be anywhere near as good as the first ones.
Place the biscuits on a cookie sheet- if you like soft sides, put them touching each other.
If you like"crusty" sides, put them about 1 inch apart- these will not rise as high as the biscuits put close together.
Bake for about 10-12 minutes- the biscuits will be a beautiful light golden brown on top and bottom.
Do not overbake.
