My mother has a special part of her pantry set aside just for these items. She usually gets them given to her by her mother. But then I cheerfully take the tins of creamed corn (nobody else I know likes this stuff, can't figure why really), stewed steak, corn relish (there's a corn theme seemingly) and tins of corned beef hash.
My own collection has recently been added to, which is a little early to decide whether you'll never use it or not I agree, but then I didn't really know what I was going to do with it when I bought it. Palm hearts. Someone on here mentioned them last year sometime and I was intrigued. I saw them in the shit-bins at Tesco for 11p so I bought not one, but two tins of them. Now they sit, waiting to be called to action. I haven't told them this, but it might be quite a while.
I notice someone else have some Reggae Reggae sauce lurking at the back of their cupboard. The thing is, not happy being very under-whelmed by his normal dipping sauce - I then went out and bought his cooking Reggae Reggae sauce too. This is keeping the Palm hearts company.
I'm a bit hooked on condiments so I have a lot and in defence they do tend to all get used. Apart from, that is, the really bad ones from the Chinese supermarket. The satay sauce dip I bought, is just oily, fishy, salty peanut butter. Shudder. That doesn't get used. Nor does it get thrown away.
I have Thai Green curry paste, a jar of minced ginger and TWO bottles of fish sauce. A friend came round and cooked me a curry. Left the ingredients and here they still remain after over a year.
