Buttermilk (or Whey or Kefir) Biscuits

taken and adapted from Mels
*great way to use up whey from strained yogurt!*

3 c. flour
1/2 tsp baking soda
1 1/2 T baking powder
1 tsp salt
9 T very cold butter cut into pieces (I just use 1 stick)
1 1/2 c. buttermilk (or kefir or 1 1/4 c. whey)

Preheat oven to 450.  Combine dry ingredients in food processor.  Add butter pieces and pulse until it looks like coarse crumbs.  Pour in the buttermilk or whey and mix just until combined.  Pour dough out onto lightly floured surface and knead slightly just folding the dough over on itself and patting.  Pat dough into a square and cut into 12-16 biscuits.  Place on lined baking sheet and bake for 10-12 min.
