How to tell if relish is bad
Smell
Fermented, yeasty or sour beyond the product's usual tang.
Texture
Separation that does not stir back, or a slimy layer.
Colour
Darkening or a change in colour at the top of the jar.
Mould
Any fuzz on the surface or lid — discard the jar.
Relish past the expiration date
Best-by and sell-by
FoodKeeper gives unopened relish 30 months in the pantry or 9 months in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Past the date
Relish past its best-by date is usually safe if stored well; check smell, look and taste before using.
How to keep relish fresh longer
- Freezing not recommended.
- Refrigerate after opening unless the label says otherwise.
- Use a clean utensil each time; crumbs and double-dipping shorten shelf life.
