To create a homemade baking mix similar to Bisquick, combine 6 cups of all-purpose flour, 3 tablespoons of baking powder and 1 tablespoon of salt in a bowl with a sifter. Use a pastry blender to cut 1 cup of vegetable shortening into the dry ingredients, then use for any recipe that calls for Bisquick.
To make the recipe, place the all-purpose flour, baking powder and salt in a bowl, and sift the ingredients together three times in the same large bowl, to ensure there are no clumps. Then, with the pastry blender, cut the cup of vegetable shortening into the dry ingredients until the mixture resembles fine crumbs. Be sure to use a solid vegetable shortening, rather than a liquid vegetable oil, as the consistency is otherwise altered.
The homemade Bisquick mix can be combined with water or milk for pancakes or biscuits, or can be left as is, and stored for future use. Store the mixture in an airtight container in a refrigerator for up to four months, as it does not contain immediately perishable products. This recipe yields 7 cups.
