2cupsshortening that doesn't require refrigeration
Instructions
Sift together flour, baking powder, salt, cream of tartar, sugar and dry non fat milk powder times.
Cut in shortening with a pastry cutter or two knives until mixture looks like coarse corn meal.
Store in covered containers at room temperature.
Notes
Notes: To measure the Master Mix, pile it lightly into cup and level off with spatula. I have used butter in replace of shortening but it must be stored in the refrigerator.
