For 4 servings
Prepare the Dried Fish and Tamarind
- If the dried fish has heads, remove and discard them. Place the fish in a bowl and pour hot water over them. Let it soak for 10-15 minutes. This step is crucial to remove sand and reduce excess saltiness.
- After soaking, gently wash the fish 2-3 times in fresh water until the water runs clear. Drain completely and set aside. Be careful not to break the pieces.
- In a separate small bowl, soak the tamarind in 1/2 cup of warm water for 15 minutes. Squeeze the pulp thoroughly to extract its essence, then strain the liquid, discarding the solids. Set the tamarind extract aside.
Sauté the Aromatics
- Heat gingelly (sesame) oil in a heavy-bottomed pan or kadai over medium heat. Once hot, add the mustard seeds and let them splutter.
- Add the fenugreek seeds and curry leaves. Sauté for about 30 seconds until fragrant.
- Add the finely chopped onions and sauté for 8-10 minutes, stirring occasionally, until they turn soft and golden brown.
- Add the ginger-garlic paste and slit green chillies. Sauté for another 2 minutes until the raw aroma disappears.
Build the Masala Base
- Add the finely chopped tomatoes to the pan. Cook for 6-8 minutes, mashing them with the back of a spoon, until they break down completely and become mushy.
- Reduce the heat and add the turmeric powder, red chilli powder, and coriander powder. Stir well and cook for 2-3 minutes until the spices are aromatic and oil begins to separate from the masala.
- Pour in the prepared tamarind extract and add the salt. Remember to be very cautious with salt. Mix everything well and bring the mixture to a gentle boil.
Simmer and Finish the Thokku
- Gently add the cleaned dried fish to the pan. Stir very carefully to coat the fish pieces with the masala without breaking them.
- Reduce the heat to low, cover the pan, and let it simmer for 10-12 minutes. The thokku will thicken, and you'll see oil floating on top.
- Once the desired consistency is reached, turn off the heat. Let the thokku rest in the pan for at least 20 minutes before serving to allow the flavors to meld and deepen.
