Instructions
💡 Tap a step to mark it doneClean the prawns thoroughly under cold running water. Remove the shells, leaving the tail intact if desired for a better presentation. Devein each prawn carefully by making a shallow slit along the back and pulling out the dark vein. Pat the prawns completely dry using a kitchen towel or paper towels. Removing excess moisture is very important to achieve that signature crispy texture when frying.
In a large mixing bowl, combine red chilli powder, turmeric powder, coriander powder, cumin powder, ginger garlic paste, lemon juice, rice flour, corn flour, and salt. Mix all the dry and wet ingredients together to form a thick, smooth marinade paste. If the mixture looks too dry, add just a teaspoon of water to bring it together. Do not add too much water as the coating should be thick and clingy.
Add the cleaned and dried prawns into the marinade bowl. Using your hands or a spoon, toss the prawns well so that every prawn is evenly and generously coated with the spice mixture. Add the curry leaves into the bowl and mix them in as well. Cover the bowl with a plate or cling wrap and allow the prawns to marinate for at least 15 to 20 minutes. For deeper flavour, you can marinate for up to 1 hour in the refrigerator.
Heat oil in a heavy-bottomed kadai or deep frying pan over medium-high heat. To test if the oil is ready, drop a tiny bit of marinade into the oil — it should sizzle and rise to the surface immediately. If it sinks, the oil is not hot enough. The ideal frying temperature is around 175 to 180 degrees Celsius. Avoid overcrowding the pan as this will lower the oil temperature and make the prawns soggy instead of crispy.
Gently slide the marinated prawns into the hot oil in small batches. Also fry the curry leaves from the marinade alongside the prawns for extra aroma and crunch. Fry the prawns for about 2 to 3 minutes on one side until they turn a deep golden colour, then carefully flip them using a slotted spoon and fry for another 1 to 2 minutes on the other side. Prawns cook very quickly, so watch them closely to avoid overcooking.
Once the prawns are beautifully golden, crispy, and cooked through, remove them carefully from the oil using a slotted spoon. Place them on a plate lined with paper towels to drain any excess oil. Fry the remaining batches of prawns the same way, ensuring the oil returns to the right temperature between batches. The fried curry leaves will add a wonderful aroma and can be served alongside the prawns.
Arrange the crispy golden prawns on a serving plate and garnish with fresh onion rings, sliced green chillies, and lemon wedges on the side. Squeeze fresh lemon juice generously over the hot prawns just before serving for a bright, tangy finish. Serve immediately while they are still hot and moru moru crispy as a starter or alongside a simple rice and rasam meal. Enjoy this Tamil coastal favourite with your family!
Tips and Tricks
- Always pat the prawns completely dry before marinating — any excess moisture will create steam during frying and prevent the prawns from becoming truly crispy. A dry surface ensures the coating adheres well and fries to a beautiful golden crust.
- The combination of rice flour and corn flour in the marinade is the key secret to achieving that extra crispy moru moru texture. Rice flour adds lightness and crunch, while corn flour helps bind the coating tightly to the prawn. Never skip these two ingredients.
- Do not overcook the prawns as they become rubbery and tough very quickly. Prawns are done when they turn pink and curl into a C shape. If they curl into a tight O shape, they are slightly overcooked. Fry in small batches at the right oil temperature for the best results.
