Instructions:
Preheat oven to 400°F. In a cup, add milk and vinegar; allow to sit at least 5 minutes or just use 1 cup buttermilk if on hand.
Meanwhile, in a medium-sized bowl, add flour, baking powder, baking soda, and salt; mix well. Add shortening and mix until dough is coarse.
Add milk mixture or buttermilk, mix fast without kneading — it is important not to knead or mix this dough a lot.
Add dough onto a non-stick baking mat or lightly floured board.
Dough should be sticky, so do not add more flour.
With a biscuit cutter or glass, quickly cut biscuits. If you like fluffy biscuits, then do not roll the dough too flat.
Place biscuits on a cookie sheet and bake for 10–12 minutes, until golden.
