I have a few depression era cookbooks, and I just loaned them to a friend to take a look at. One of them is Clara's Kitchen. She's passed away since it was written. My go to basic books for scratch recipes are Mennonite and Amish Cookbooks. Mostly those spiral bound ones that churches and schools put out. Mennonites specialize in "no waste" and frugal cooking. Cookbooks called, "What to do with powdered milk?", and small cookbooks that are just one type, like, "Crackers". I have a floor to ceiling bookshelf of cookbooks. I love cookbooks. Also a large collection of canning cookbooks. I have, "Dining during the Depression", too. And a good assortment of dutch oven outdoor cookbooks.
