Pretty good shape for weeks or months. First eat the stuff in Refrigerator, and start canning frozen stuff on rocket stove.
Generator will keep food from spoiling long enough for that. If we cycle that, it will do even longer.
Later, for keeping food for a day: Metal kettle or can put food inside. Set it in the bathtub, and wrap it up with dripping wet towels or burlap bags. Evaporation will cool it.
I have a pressure canner and have been pressure canning soup stock for years.
Whenever we have Thanksgiving dinner I cook down the turkey carcass and make soup out of it. I can only the broth and meat and leave the veggies out until I actually make the soup.
I don’t like the way the veggies come out when canned but also know how to do that and would do it for survival if necessary. Canned veggies are better than no veggies.
So I have quite the stock of canned turkey, beef, and chicken soup started.
I do grow my own veggies but considering what NY summers are like and my ability to have only so much garden space, I am grateful we don’t have to depend on that for survival.
I also have a grain mill and wheat berries so can make homemade bread if need be.
Always eat the ice cream first!
