One method of storing away extra food for lean times is in the freezer. While not suitable for long-term storage (especially in a situation where power is unreliable/unavailable), in our current situation, where grocery prices seem to increase every day, it’s a viable alternative, especially for things like meat.
Clemson University‘s Extension group has a Home and Garden Information Center full of handy information, including a guide to food storage in the refrigerator and freezer. I’ve printed out a couple of copies, one for the fridge and one for the freezer. You might want to consider doing the same for future reference.
