Rumford's Baking Powder Biscuits

From the back of a can of Rumford Baking Powder.
2 cups flour
3 teaspoons aluminum-free baking powder
1 teaspoon salt (more if whole wheat flour is used)
6 tablespoons unsalted butter or shortening
2⁄3; cup milk (more as needed)
Directions:
PREHEAT oven to 450 degrees.
Combine flour baking powder and salt together in a large bowl.
Cut in shortening until mixture resemble coarse meal.(use food processoer if desired)
Add milk to make a soft dough.
Turn dough out on a floured surface and knead for 12 turns (30 seconds)
Roll out to 1/2 inch to 3/4 inch thickness.
Use a cookie cutter to cut out into rounds. I used a 3-inch diameter canning jar
Place on baking stone
Bake approximately 12-15 minutes or until light golden.

At the last minute I rolled in some more sugar and milk and flour and made scones.
