Food Storage Substitutions:

Brown Sugar = 1 c. white sugar + 1-2 T. molasses
White sugar and molasses are already on our list of storage items, so if you plan to store brown sugar as well, just store a little extra of these items. Molasses has a longer shelf life than brown sugar, and you don’t have the problem of it getting clumpy and hardened since you will be making it fresh.

Buttermilk = 1 c. milk or powdered milk + 1 T. vinegar
This is so much easier than having to keep buttermilk or powdered buttermilk on hand when you need it for a particular recipe. Vinegar can also be used in baking recipes, to improve your bread recipes, as well as for homemade cleaning supplies. So these two items should definitely be part of your food storage already!

Baking Powder = 1 tsp. baking soda + 2 tsp. cream of tartar
While you may not think of storing cream of tartar, this actually makes a lot of sense. Both baking soda and cream of tartar can have an indefinite shelf life if stored in airtight containers at room temperature. Baking powder, however has a short shelf life of 6-12 months. To test if your baking powder is still active, stir 1 teaspoon into ½ a cup of hot water. If it doesn’t bubble, it will need to be replaced.
