Easy Biscuit Mix

I have a hard time finding this recipe from AllRecipes.com each time I want to use it, so I'm saving it here now.  I mostly use it as a base for cheddar bay biscuits.  It's essentially just homemade Bisquick.

Ingredients
10 cups all-purpose flour
1/2 cup baking powder
1/4 cup white sugar
2 tsp salt
2 cups shortening

Directions

1. In a large bowl mix together the flour, baking powder, sugar, and salt. Cut in shortening until mixture resembles coarse crumbs. Better yet, use a large food processor.  Blend dry ingredients first, then add shortening and pulse until it looks mealy.
2. Store in an airtight container for up to 6 weeks.
