Tinned anything was very much a case in teh ration packs I used to play around with in my air cadet days
- Tinned sausages, about half a dozen in a tin full of lard
when warm, worse when cold
- cheese and butter, meh
- unrecognisable stews, generally ok with copious application of S&P and herbs
- oatmeal blocks and mixed fruit pudding - I'd sell my own soul for those, or even my first born
As for tinned potatoes, I'm going camping next week, and whilst I've added fig rolls to my list, I'm not expecting zombies, and tinned spuds are useless against midges, so they'll be staying where the should be - nowhere near me.
