All I see are boxed instant potatoes now, but we used to be able to buy them in a can. Anyone able to purchase some at their supermarket without special ordering through Honeyville or one of the dried food places?
Cash & Carry, a bulk food store here sells em in a #10.
I prefer the pouches as all they need are hot water. No margarine or butter to add and many different flavors. One packet is big enough for the wife and I if we have another dish to go with it. Also they fit nice in my patrol pack. On the negative side they don't have the shelf life of a #10. Can't have everything.
Canned mash potatoes? Why not just get a bunch of tasty seed quality potatoes. Then you can make your own mashed potatoes and can grow practically an endless supply of new ones to replenish your stores.
Also sauerkraut is extremely easy to make. You just need a big jar or pot, cabbage and some sea salt.
