Chettinad Sura Karuvadu Varuval
Spicy dry-fried salted shark meat, a coastal Chettinad delicacy.
About this dish
Karuvadu (dried fish) is a staple in Chettinad and coastal Tamil Nadu, prized for its intense umami and long shelf life. This specific preparation uses Sura (Shark) which is salted and sun-dried, resulting in a firm texture that doesn't disintegrate. It is a pungent, spicy, and tangy dry-fry that acts as a powerful appetite stimulant during the monsoon months.
Ingredients
For Fish Prep
- 200g Salted Dried Shark (Sura Karuvadu)
- 1/2 tsp Turmeric powder
- Hot water for soaking
The Aromatics
- 4 tbsp Gingelly oil
- 1 tsp Mustard seeds
- 1 tsp Split urad dal
- 15 Garlic cloves, crushed with skin on
- 2 large Onions, finely chopped
- 2 sprigs Curry leaves
Spices and Tang
- 2 tbsp Chettinad Kuzhambu Milagai Thool (or 1 tbsp chili + 1 tbsp coriander powder)
- 1/2 tsp Turmeric powder
- 1 tbsp Tamarind paste (thick extract)
- Small pinch of Salt (Salt with caution as fish is salted)
Method
- 1
Clean the dried fish
Soak the dried shark pieces in hot water with 1/2 tsp turmeric for at least 20 minutes. This softens the meat and removes excess surface salt and grit. Scrub the pieces gently and rinse in cold water 3-4 times until the water runs clear.

Dry and chop
Pat the fish pieces completely dry with a paper towel. Cut them into bite-sized 1-inch cubes. If the pieces are too large, the centers will remain salty and tough.

Temper the oil
Heat gingelly oil in a wide pan until it shimmers. Add mustard seeds and let them splutter, followed by the urad dal. Wait until the dal turns a light golden brown, which provides a nutty crunch to the dish.

Sauté garlic and curry leaves
Add the crushed garlic cloves and curry leaves. Fry the garlic on medium heat until the edges turn golden; the skin-on garlic adds a rustic, smoky aroma essential for Karuvadu dishes.

Brown the onions
Add the chopped onions and sauté until they are translucent and starting to brown. The onions should be plenty, as they form the 'masala' coating for the fish.

Add the fish pieces
Add the cleaned shark pieces to the pan. Fry them in the oil for 5 minutes before adding any spices. This firms up the texture and removes any lingering raw smell of the dried fish.

Spice infusion
Add the Kuzhambu Milagai Thool and a pinch of turmeric. Toss well to coat the fish. Be extremely careful with salt; taste the fish first, as the residual salt in the shark is often enough for the whole dish.

Tamarind glaze
Drizzle the thick tamarind paste over the mixture and toss. The acidity of the tamarind balances the saltiness of the fish and the heat of the chilies. Cook on low heat for another 5-7 minutes until the oil separates.

Finish to a crisp
Continue to fry on low heat, stirring occasionally, until the moisture has completely evaporated and the masala clings tightly to the fish. The fish should be slightly crispy on the outside but chewy inside.
Notes & variations
- Always wash Karuvadu multiple times; the drying process often happens in open areas.
- If you don't have shark, dried kingfish (Vanjaram) is an excellent substitute.
- Do not add water while cooking; the oil and onion moisture are sufficient for a dry Varuval.
- Store in an airtight glass jar; the flavors intensify after a day.
Serve with
Perfect with Old Rice (Pazhaya Sadam) or Curd Rice and a simple Keerai Masiyal.
Cook's note
Crushing the garlic with the skin on is a traditional technique that prevents the garlic from burning and adds a unique earthy flavor.
