Q: How long does Rasam Powder last?

In the pantry: 9–12 months. In the freezer: Up to 3 years. Sealed / unopened: 1–2 years (pantry, unopened, cool and dark). Store in a cool, dark cabinet and screw the lid on tightly right after use to retain the pepper and cumin aroma. Smaller, fresher batches taste best in warm, humid kitchens.

Why guidance varies

Mostly dried pepper, cumin, coriander, and lentils, so the safety risk is low, but the volatile aromas fade with exposure to oxygen and warmth, giving flat-tasting rasam. Humidity causes clumping and occasional pests.
