Yes. Tamarind lasts 6 months in the fridge and 1 year in the freezer. After that, or sooner if stored badly, it spoils: watch for the signs below.
How to tell if tamarind is bad
Smell
Fermented, sour or musty odour.
Texture
Soft, mushy or leaking spots, or wrinkled skin with soft flesh.
Colour
Dark bruising that spreads, or browning inside.
Mould
White, grey or green fuzz — discard soft produce; cut firm produce generously.
Tamarind past the expiration date
Best-by and sell-by
FoodKeeper gives unopened tamarind 1–3 weeks in the pantry or 6 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
Tamarind past its best-by date is usually safe if stored well; check smell, look and taste before using.
How to keep tamarind fresh longer
- Refrigeration guidelines apply to just the pulp.
