Query: Disappointed but maybe I am wrong

I think that people who buy this book should know that many of the recipes require the use of a cake mix. It may be that when I actually make the cakes, I will regret what I write now, but until then I am feeling a little short changed. Surely Mrs. Pregnall does not use commercial cake mix in her own shop.
