I can believe it. More than a decade after the Depression, my grandma saved money by feeding my dad and his brothers watered-down reconstituted powdered milk. There was an entire category of foods my grandpa didn't allow in their house because he ate them as a child in the Depression, including turnips, rutabagas, millet, and certain kinds of beans, but they still felt like they couldn't afford to use the full ratio of milk powder.
