Cockles or thisra, as we call them in Bombay and Pune are one of those shellfish that most of the world overlooks. That’s their loss. These larger clams, cooked in a red coconut milk curry with kokum and jaggery, make a dish that is quietly spectacular: tangy, a little sweet, warming from the chillies, and deeply satisfying with a mound of plain rice.
This is my recipe, and it appears in both of my sister Abby’s Gourmand award-winning cookbooks — Jevayla Ye and Essentially East Indian Seafood.
What Are Thisra (Cockles)?
Thisra are the East Indian name for cockles — a bivalve shellfish with a distinctive ribbed shell. They’re larger and meatier than the small European cockle you might find at a UK seaside stall, and they have more chew than regular clams. In Mumbai’s fish markets, they’re sold fresh with shells on and are a staple in East Indian cooking.
If you’re outside India, look for cockles at a Chinese or Southeast Asian grocery. If you can’t find them, small clams are a reasonable substitute, though the texture will differ slightly.
If you’ve cooked mussels before, the approach here is similar — the key differences are the longer boil time needed to clean them and the distinctly East Indian spice base, which has nothing in common with a South Indian masala or a Rick Stein-style mixed shellfish curry.
What Makes This an East Indian Recipe?
The spice base of red chillies, garlic, and cumin ground with coconut milk is a signature of East Indian cooking. So is the kokum, the dried sour fruit that adds a dark, fruity tartness that tamarind can approximate but never quite replicate. The jaggery at the end balances everything: a whisper of sweetness that rounds out the heat and sour.
This is not a heavy curry. The gravy is medium-bodied, red, and aromatic — it coats the cockles without overwhelming them.
A Note on Prep
The most important step is the cleaning. Cockles live in sand, and if you skip the washing you’ll end up with grit in your curry. Boil them first, let them cool, then wash very thoroughly. You can remove the cockle meat entirely from the shell, or keep them half-shell — which is how I usually serve them, because they look really beautiful arranged around a mound of rice.
How to make Spicy Thisra (Cockles) Curry Step by Step
1. Gather your spices Lay out your red chillies, garlic cloves, and cumin seeds — these form the base of the masala paste.
2. Make the masala paste Grind the red chillies, garlic, cumin seeds, and coconut milk together to a smooth red paste.
3. Prep the cockles Boil the cockles until they open. Once cooled, wash them very thoroughly to remove any sand and grit. You’ll see them in their shells at this stage — keep them half-shell for serving.
4. Soak the kokum Soak the kokum rinds in a little water to soften them and release their colour and tartness.
5. Dice and fry the onions Finely dice the onions and fry in ghee or oil until deep golden brown — don’t rush this step, the colour builds the base flavour of the curry.
6. Add the masala Add your ground red masala paste to the fried onions and cook for 5 minutes until the oil separates and the raw smell is gone.
7. Add water and simmer Add water and salt, bring to a boil, and simmer for 5 minutes.
8. Add the cockles, kokum, and jaggery Add the cleaned cockles, softened kokum, and jaggery. Simmer for 15 minutes until the gravy reduces and deepens in colour to that rich red-orange.
9. Finish with coconut milk Stir in a little more coconut milk and cook for a few more minutes to round out the gravy.
10. Serve Arrange the cockles around a mound of steamed rice and spoon the curry over. Garnish with a sprig of coriander if you like.
Serving Suggestions and Tips
- Serve with boiled rice or apas, the East Indian rice handbreads. If you’re exploring East Indian shellfish cooking, my prawn chilli fry is another good place to start.
- You can use tamarind juice instead of kokum if kokum isn’t available to you — use about 1–2 tablespoons of thin tamarind water.
