Just finished reading alas Babylon have a few questions RE food

[Skean Dhude]

From the top...

There is information available about storaging and preserving, salting, drying, etc. You need to use as many as you need for both meat and veg.

I'm not in favour of caching in areas you do not control. Simply dig a big hole in your garden and bury your carefully prepared and wrapped preps in it. No perishables. If no garden then consider false walls, roof, etc. Perhaps consider renting somewhere secure, what about relatives?

Rotation is difficult but rotate what you can and most tinned foods will last a few years anyway.

You can only do so much and your situation makes it difficult.
