Common questions
How long does pectin last at room temperature?
Until the package use-by date (1 month once opened) in a cool, dry pantry.
How can I tell if pectin has gone bad?
Throw it out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
