Beautiful fresh prawns turned into chewy rubber bullets? Prawns are one of the easiest proteins to cook — and to ruin. The difference comes down to one thing: time.

You've had it happen: beautiful fresh prawns turned into chewy, rubbery little bullets. The frustrating truth is that prawns are one of the easiest proteins to cook — and one of the easiest to ruin. The difference comes down to one thing: time. Here's how to get perfectly tender prawns every single time.
Prawns cook incredibly fast. Unlike chicken or mutton, they need only 2-3 minutes total. The moment they go past this, the proteins tighten and squeeze out moisture — giving you that dreaded rubbery texture. When it comes to prawns, undercooking slightly is far safer than overcooking.
This is the single best visual cue. Raw prawns are straight or slightly curved. As they cook, they curl into a "C" shape and turn pink. That's your signal they're done. If they curl into a tight "O", they've overcooked. Pull them off the heat the instant they form a loose C.

There are two safe zones for prawns. Fast: high heat for 2-3 minutes (stir-fry, tawa, grill). Slow: gently simmered in a curry where they poach in the gravy. The danger zone is medium heat for 5-10 minutes — long enough to toughen, not long enough to break down. Pick a lane.
For prawn kuzhambu or masala, cook your entire gravy first — onions, tomatoes, spices, everything. Add the prawns only in the last 5-7 minutes. They'll poach gently in the hot gravy and stay juicy. Adding them at the start guarantees rubbery prawns by the time the curry is ready.

Pat prawns completely dry before frying — wet prawns steam instead of sear. Don't crowd the pan; cook in batches so they fry, not boil. For grilling or tandoori, marinate 15-30 minutes in curd and spices to tenderise. And always buy prawns that are already deshelled and deveined — it saves 30 minutes and means you can cook the moment inspiration strikes.
