Common questions
How long do marshmallows last in the pantry?
1 year from the date of purchase. 1 month after opening.
How can I tell if marshmallows have gone bad?
Throw it out if it smells off, feels slimy or sticky, shows mold, or has changed color. Storage times assume it was handled safely and kept cold the whole time.
