We try to (and succeed if I may brag) stash a years supply of food!! I do soups,sauces, all preserves, veg,meat, freeze goats milk, dry herbs, bake all I can when eggs are good, goats cheese, breadcrumbs etc , nothing processed apart from an odd tin of beans here.I make breads so extra batches for the freezer. So we do stash makings ie flour etc
We also dig our own peats which supply the rayburn for cooking , water and heating. We make our own hay and silage for the year if that counts
We have a fishing boat so we catch our own fish, we have creels but not keen on crab and lobster!
Basically when you run a croft you work all summer to keep you for winter and prepare all winter for summer.
We have a properly done out well courtesy of the water board which is piped up but needs 'sorting' legally. Sewage is an old type sesspit thing, works well so far. We have candles but much prefer oil lamps.
But the best of all a good bartering system. It is amazing what you can get in return for my OH servicing a boiler.(heating kind!)
