How to Store Karuvadu for Maximum Freshness
Why Storage Matters More Than People Think
One of the biggest advantages of karuvadu over fresh fish is shelf life — traditionally sun-dried fish, stored correctly, stays good for 4 to 6 months. But moisture is the enemy: even a little humidity can undo weeks of careful sun-drying.
The Basics: Cool, Dry, Airtight
Always store karuvadu in an airtight container — a glass jar with a tight lid or a zip-lock bag both work well. Keep it in a cool, dry place away from direct sunlight and away from the stove, where steam and heat can introduce moisture.
Avoid storing it in the same container as onions, garlic, or other pungent items, since dry fish absorbs odours easily.
For Longer Storage, Use the Refrigerator
If you've bought in bulk or want it to last beyond a couple of months, refrigeration is your best bet. Pack the karuvadu in a sealed container or bag before placing it in the fridge — this prevents it from drying out further or picking up smells from other food.
For very long-term storage (6+ months), the freezer works too. Just bring it back to room temperature before cooking for the best texture.
Signs Your Karuvadu Has Gone Bad
Good karuvadu should smell like the sea — clean and salty, not sour or musty. If you notice a sour smell, visible mould, or a sticky/soft texture instead of the usual firm, dry feel, it's best to discard it.
Buying from a source that sun-dries without chemical whiteners — like our Rameshwaram-sourced range — also means fewer surprises, since there are no artificial preservatives masking spoilage.
