Lately, I have developed a dislike of buying preprocessed, overpackaged convienence foods. If I want cookies, I will bake them. Pudding isn't THAT hard to stir up and sitting at the stove can be very peaceful and meditative. The only cake mix I buy is Angel Food, since I have made it from scratch, and there is really very little difference in the quality of the finished product.
I have found, from time to time, favourite recipes of mine call for premade biscuit mix. I don't make a habit of buying that, but I learned it is easily made from very common pantry ingredients. Once you know the secret, you will stop buying it too!
I used the following recipe to make dumplings for stew last night. They turned out perfectly and I didn't have to make a last-minute trip to the store!
