What is Karuvadu?

Karuvadu is the Tamil word for dry fish — fish that is cleaned, salted, and sun-dried to preserve it. It is widely used in Tamil Nadu and coastal South India to make spicy curries, thokku, and side dishes. Karuvadu is known for its bold, intense flavor and long shelf life. 

What is Karuvadu?

Karuvadu (கருவாடு) is a traditional method of preserving fish by salting and drying it under the sun for several days. This process removes moisture, enhances flavor, and allows the fish to be stored for months without refrigeration.

It is one of the oldest food preservation techniques in Tamil culture. Coastal regions like Rameswaram, Tuticorin, and Nagapattinam have relied on karuvadu for generations — not just as food, but as an essential part of everyday cooking.

Types of Karuvadu

• Nethili Karuvadu (Anchovy) – Small, crispy, and perfect for fry and thokku
• Vanjaram Karuvadu (Seer Fish) – Meaty and rich, milder smell
• Kelanga Karuvadu (Catfish) – Strong flavor, used in bold curries
• Viral Karuvadu (Murrel) – Thick and fleshy, ideal for kuzhambu
• Kavalai Karuvadu – Medium flavor, good for everyday cooking
• Sura Karuvadu (Shark) – Dense and chewy, used in traditional recipes

How to Eat / Use Karuvadu

• Cook into karuvadu kuzhambu (tamarind-based curry) with rice
• Prepare karuvadu thokku — a spicy, oil-based side dish
• Fry small fish like nethili for a crispy side
• Add small amounts to sambar or rasam for extra depth
• Mix with rice to make karuvadu sadam

Tip: Soak in water for 15–30 minutes before cooking to reduce saltiness and soften texture.
