What is the shelf life of packaged pudding and the shelf life of canned mussels?!
Answers: Canned seafoods typically have a shelf life of 24 months while canned (or sealed) products containing dairy typically have a shelf life of 9-15 months depending on if they are refrigerated or not.
Canned things last forever! And is the pudding dry or ready-to-eat? I'd say either way there are probably enough preservatives that it'll be good for a year ready-to-eat and forever dry.
