Most grocery stores stock No. 10 cans in the institution section.
I wait for sales on smaller cans and buy what I need. A No. 10 can of beans is a whole lot of whoopie cushion.
One can also buy small freeze-dried packages of spuds, dried soups and cake mixes. I find them more sensible than No. 10 cans. I just can’t see myself baking a cake that’s 10-feet long.
Everyone's needs are different.
Common sense will help you make the right decision.
I’ve been storing the small 99cent packages of Martha White muffin mixes. You only have to add water, they have cornbread, strawberry, blueberry and wild berry muffin mixes and biscuits.
You can add milk as well but you don’t have to. I figure it is one way to get bread quick and easy, even if it has to be over an outdoor fire.
I have also been storing dried and evaporated milk. Lots of other things of course but I wanted to specifically cover some type of bread because I sure will miss the bakery goods and I’m not a “from scratch” baker.
We also store spam, canned chicken, tuna, han, dried and canned potatoes, all kinds of canned vegetables, soups, gravies, (to go with the rice and beans), pasta, water, coffee, tea, canned juice and fruit, and ammo.
I freeze all my boxed or bagged mixes (muffins, pancake, waffle,rice, beans)for at least 24 hours before I store it (suppose to kill bugs).
If nothing bad happens it will still go to good use.
