When I first got married, I dutifully got on the Bisquick train. Once the kids started coming, I tried to make as much as I could from scratch to avoid preservatives and unnecessary ingredients. Bisquick was a tough one to let go of. Fortunately, I came across a recipe for biscuits years ago that solved my "need a homemade Bisquick recipe" problem. I figured that if it could make biscuits, then it could make all those other tasty Bisquick recipes. And it does. I make a big batch and then keep it in an air-tight container in the refrigerator to use when needed. So if you are Bisquick lover, you'll appreciate this post. And if you are not familiar with Bisquick, I will be sharing some tasty recipes in the future.
6 cups unbleached all-purpose flour
4 cups cake flour
3 Tablespoons baking powder
2 Tablespoon kosher salt
1 cup vegetable shortening, cold and cut into 1/2-inch cubes
In the bowl of a 14-cup food processor, pulse together both flours, baking powder, and salt until combined. Scatter the vegetable shortening over the flour mixture and process until completely blended. Use immediately or store in an air-tight container in the refrigerator. Enjoy!
