The library was featuring cookbooks this week and one was The Storm Gourmet: a Guide to Creating Extraordinary Meals Without Electricity by Nikolopoulos. She’s from Florida so her thing is hurricanes but any storm will do. It’s full of meals you can make with shelf stable and some fresh foods (onions etc) so that in a (presumably sheet term) grid down situation you don’t have to just eat canned beans. It also has several helpful reference charts. While I rarely use those kind of foods and I eat a plant based diet I could substitute some things and have my version of shelf stable foods (home canned potatoes instead of store bought etc) so it’s a good resource
a book I own is Apocalypse Chow: How to Eat Well when the Power Goes Out (or a different subtitle for a different edition but similar thought) by Jon and Robin Robertson Which is a similar book for vegetarians. She writes a lot of cookbooks so it would be good food. Meat eaters could add canned meat to the recipes just as I would remove them from the othe book’s recipes. Again I would substitute for some store bought stuff just because I am persnickety. But they are interesting books.
Caution! do not just order Apocalypse Chow as a title or you might end up with some novella.
And a note: Florida power and light had several post hurricane outages over two weeks and at least one over five weeks.
