Right but what if the cheapest food is idk, something like celery root? I think the idea w/the thesis of the article is that a skilled cook can adapt to whatever ingredients are cheapest at any moment.
I think I’m a decent cook but I also think I need to improve because when I’m in the produce area and have no idea how to use like 15—20% of the options there. E.g. celery root, cactus, and ½ dozen things I don’t even recognize.
Sorry, but my point was even shopping cheapest only is getting too expensive now. Poor people have always been buying cheap produce only. That strategy doesn't help when the floor for prices is rising. So if something as basic as cheap as cabbage—the canonical broke peasant food—is like $1.25/lb where it used to be $0.25/lb, the problem isn't the %15-20 of vegetables you don't know how to cook!
