You spurred me to have a look in the back of my cupboard Elim.
Hoi Sin sauce - 12/31/2023
Tin of stuffed vine leaves - 9/30/2019
Gyoza sauce - 12/19/2015
Tin of red salmon - no date but at least 3 years old.
All unopened.
I would have no problem using any of them, maybe not the gyoza sauce, but definitely the salmon. Tinned food lasts decades.
