How old is the oldest item in your store cupboard?

[Delphiniumandlupins]

Following on from a thread about mustard powder, what's the oldest product in your store cupboard? I regard BBE dates as advisory, rather than a rule (obviously Use By are stricter).

It used to be traditional to keep the top tier of a wedding cake for the first christening (when everybody had fruit cakes) so mine had new marzipan and icing 10 years later.

We had some old dettol antiseptic which was probably 10 years old and gone a funny dark brown colour, I think DH was still using it, I bought new and use the old stuff for cleaning the bins

DH has a tin of caviar that he bought as a student in Russia in 1993, it’s going in his coffin.

DH Mother has a jar of jam that her Mother made in 1962.

Allspice- large container from the Turkish grocer 2018

I use it in pancakes and muffins all the time! Anything that needs cinnamon gets some. I think it's either magic or breeding.

I have a partly-used pack of sugar flowers stuck to greaseproof paper, purchased from Sainsburys when I was a child, and helping DM to decorate fairy cakes. I always wanted to keep the flowers though and not use them, so tended to use hundreds & thousands instead. They date from circa 1970, are now rock hard and could probably be used as ammunition against the zombies alongside the tin of fish belonging to @Yello24

Recently found a stash of tins in my garage for when I was prepping for Covid, lol. Think soup from 2020, etc

We had a new kitchen a while back and wgev removing the old cupboards we a spice jar (can't recall what spive it was) from 2013 Not even sure it was ours cosdidn't live here in 2013. We also found a full unopened packet of cigarettes that was so old it didn't have any warning labels on it.

Flour 2012. I used it to bake a cake last week!

Angel delight chocolate flavour.
2016.
I imagine it would be ok to eat still. It's not sugar free and sugar must be 97%of the ingredients

I'm loving so many of these examples, from the gifted/inherited items to the shops no longer trading. Also, the imaginative uses for things which are past their best - no need to bin things which can be used for pest control, cleaning or defeating zombies.
