Buttermilk Biscuits

These went over VERY well when I made them last week. Very light and fluffy.
I had to add an extra 3/4 cup for altitude up here, but this recipe worked perfectly as is when I was in Texas.

2 cups flour
1/2 teaspoon salt
1 cup buttermilk
5 tablespoons butter or shortening (butter flavor)
3 teaspoons baking powder
1/4 teaspoon baking soda

Mix flour, baking powder, salt and baking soda in a bowl. Cut in butter or shortening. Add and very gently mix in buttermilk, kneading it. Turn dough onto a floured board and pat to a thickness of 3/4". Cut with biscuit cutter and place on ungreased cookie sheet. The key to light, fluffy biscuits is to be very gentle with the dough.
Bake at 450 for 10-12 minutes until lightly browned.
