There are plenty of ways besides couponing that can save you lots of money on your groceries. Sure it may be a great deal to combine a sale on Bisquick with a coupon that can double. But what if, by spending just a few minutes, and using ingredients you already have on hand, you can make your own for just pennies. This is where you can see the biggest difference in your grocery spending habits. The added benefit of making your own products is knowing exactly what is in the product. I have been doing this with some of my groceries for a while. This recipe is one I use often. With a family this size you need to use convenience foods to make life easier. You just don't need to use THEIR version. The recipe makes a couple of months worth of baking mix and can be used for dozens of recipes. You can go to the Bisquick site to get them all. I store mine in an airtight container in the darkest and coolest section of my pantry.
Homemade Bisquick Mix8 cups flour

1/4 cup baking powder
1 tablespoon salt

Combine flour, milk, baking powder and salt. Cut in shortening. Store in tightly closed container in cool place. Use anywhere Bisquick or other biscuit baking mix is called for.
I suggest using your electric mixer for this recipe. My refurbished Kitchenaid works great with this.
