Sun drying works too @gingbabida! What country are you from?
We have 6 months of winter in Canada which means that we can only really grow food now during our summer (End of May to mid-October).
So, I am in the middle of storing fresh produce now so that we can eat nutritiously in January.
I don’t have to do this...but am choosing to, in an effort to learn how, so that if I ever seriously have to, I can. ;)
Everyone should know how to preserve and store food.
Basic survival.
