Dried mixed herbs
One roasted carcass with a bit of meat left on it
Pearl barley
Chopped onion
Salt to taste.
Cover with water, bring to the boil and simmer for about 3 hours. Cool and de-bone.
Quantities vary according to the size of the carcass.
Chicken: 1 medium onion, 2 handfuls of pearl barley, 1 tablespoon of herbs.
Turkey: double the above.
Add the salt before the simmer, but not too much, so you can salt to taste at the end.
If you reboil for at least 3 mins each day it’ll last for ages without going in the fridge. Kind of like a hunter’s pot.
