Ingredient Breakdown

The heart of this recipe lies in using fresh tiger prawns, known for their firm, meaty texture and delicate sweetness. They hold up beautifully in the spicy masala, absorbing the flavors while maintaining their juiciness. For the spice mix, whole cumin, fennel, coriander, black peppercorns, and red chilies are toasted to release their natural oils, creating the signature Chettinad aroma that’s earthy, smoky, and complex.

Aromatics like onion, ginger, and garlic build the base of the curry. They are slow-sautéed until golden, adding sweetness that balances the intensity of the spices. The blended tomatoes give the dish body and tang, while a touch of desiccated coconut adds a mild nuttiness that smooths out the fiery edge. The tempering of curry leaves, cinnamon, and cardamom infuses the oil with a fragrance that instantly identifies the dish as distinctly South Indian. Each of these elements plays a vital role in creating a harmonious balance between heat, richness, and depth.

Step-by-Step Preparation Guide

To begin, the spice mix is carefully toasted in a dry pan until aromatic. This step is crucial, as the gentle roasting coaxes out the oils hidden in the spices, enhancing their natural flavors. Once cooled, the spices are ground into a fine powder that will form the backbone of the masala.

Next comes building the curry base. Coconut oil is heated in the pan, and the tempering ingredients—cinnamon, cardamom, and curry leaves—are added, releasing their aroma instantly. Finely chopped onions are cooked until caramelized and golden, followed by the addition of grated ginger and garlic, which infuse the curry with warmth and complexity.

The roasted spice powder is then added along with the blended tomatoes and salt, creating a thick, deep-red masala. As it simmers, the oil begins to separate from the mixture—a sign that the spices have fully bloomed and the base is ready. At this stage, the prawns are introduced and gently stirred through the sauce, followed by a splash of water to create a luscious consistency. The curry is cooked just long enough for the prawns to turn pink and tender, ensuring they remain juicy. A garnish of fresh coriander provides a final touch of color and freshness.

Recipe Tips

Roasting spices on medium heat ensures flavor without bitterness. The goal is fragrance, not charring.

Avoid overcooking prawns to keep them tender and succulent. They only need a few minutes once added to the curry.

Use fresh curry leaves and coconut oil for authentic Chettinad flavor. These two ingredients define the dish’s aroma.

If the curry becomes too thick, add a splash of hot water to loosen the consistency. It should be velvety, not too dry.

What to Serve With This Recipe

Prawn Chettinad pairs beautifully with steamed basmati or jeera rice, which helps absorb the robust, spicy gravy. Soft chapatis, flaky parathas, or even appam make excellent accompaniments for soaking up every drop of the curry. A side of cooling cucumber raita or coconut chutney provides relief from the heat, while lemon wedges or a simple onion salad add brightness and crunch. For a complete South Indian-inspired meal, serve it alongside crispy papadums or plain dosa.

Creative Variations

To make the curry richer, add a spoonful of coconut milk at the end for a creamy, mellow finish. For a vegetable-forward version, toss in okra or bell peppers, which complement the spicy masala beautifully. If you crave extra heat, increase the number of dried red chilies or sprinkle in more crushed black pepper. For a lighter version, replace tiger prawns with shrimp or small prawns—they cook faster and absorb the flavors just as well. Each variation offers a slightly different take on this traditional favorite while keeping its bold character intact.

Ingredients

Ground Spice Mix

1 tsp cumin seeds
1 tsp fennel seeds
1 tsp coriander seeds
2 tsp whole black peppercorns
3 dried red chilies (hot variety)
½ tsp desiccated coconut

For the Curry

2 tbsp coconut oil
1 cinnamon stick
3 cardamom pods (lightly crushed)
5 curry leaves
1 large onion, finely chopped
10 g fresh ginger, grated
4 garlic cloves, grated
300 ml blended tomatoes
650 g tiger prawns, peeled and deveined
¾ tsp salt
100 ml water
Fresh coriander, chopped (for garnish)

Instructions

Begin by preparing the spice blend. In a heavy-bottomed pan or karahi, dry roast the fennel seeds, cumin seeds, coriander seeds, black peppercorns, dried red chilies, and desiccated coconut over medium heat. Stir continuously for about 5 minutes, ensuring the spices toast evenly without burning. Once aromatic, remove from heat and allow to cool slightly before grinding the mixture into a fine powder using a spice grinder or mortar and pestle. Set aside.

In the same pan, heat coconut oil over medium heat. Once hot, add the cinnamon stick, crushed cardamom pods, and curry leaves. Let them sizzle for a few seconds until fragrant, releasing their natural oils into the pan.

Add the finely chopped onions and sauté until they turn golden brown, stirring often to prevent sticking. Next, stir in the grated ginger and garlic, cooking for 1–2 minutes until their raw aroma fades and the mixture becomes aromatic.

Pour in the blended tomatoes and add the prepared ground spice mix along with salt. Stir well and let the mixture simmer over medium heat for about 10 minutes. The curry base is ready when the oil begins to separate from the masala and rise to the surface, indicating the spices have fully bloomed.

Add the cleaned prawns to the pan, followed by 100 ml of water. Mix gently to coat the prawns in the rich masala sauce. Cover and cook over low-medium heat for about 10 minutes, or until the prawns turn pink and tender. Avoid overcooking to maintain their soft, juicy texture.

Garnish with fresh coriander and serve hot. The result is a deeply aromatic and spicy South Indian-style prawn curry with layers of roasted spice, tangy tomato, and subtle coconut undertones—perfect with steamed rice or paratha.
