Devein, wash and pat dry prawns. Measure 1/2 tsp turmeric, 1 tsp Kashmiri chilli powder, 1 tbsp chopped ginger, 1 tbsp chopped garlic, 3/4 tsp of salt. Sprinkle over prawns and rub. Keep aside for 15 to 20 minutes.
Meanwhile boil water in a saucepan. Once water comes to a boil, add 8 tomatoes and cook until skin bursts. Take out tomatoes with a slotted spoon and immerse in a bowl of cold water. Drain, peel the skin, chop roughly and blend in a mixer.
Heat a kadai, add 3 tbsp of ghee and fry prawns. Keep aside.
Now in the same kadai, add 3 tbsp more of ghee. Add the rest of the chopped ginger and garlic and saute for 2 minutes. Now add the spice powders and saute for 2 minutes. Add tomato puree. Cook until oil starts to leave the sides of the pan. Deglaze the pan with 1/2 cup of fresh chicken stock or water several times.
Add 1.5 cups of water and bring it to a boil. Add fried prawns and simmer for 10 minutes. Add more water or stock to achieve the desired consistency.
Garnish coriander leaves, julienned ginger and split green chillies.
Prawns - 1 kg of prawns yields 500 gms after cleaning. Use fresh water prawns for best results. Clean and devein the prawns thoroughly before marinating.
Ginger and garlic - Used finely chopped Indian ginger and garlic for maximum flavour.
Tomato puree - I prefer to substitute half quantity of blanched and pureed fresh tomatoes with storebought strained tomatoes. Puree from 4 blanched tomatoes and 200 gms of strained tomatoes tin or pack for rich tomato gravy.
Cumin powder - Dry roast cumin until slightly warm and powder in a dry grinder. Use freshly ground cumin powder for max flavour. Ground cumin can be stored at room temperature in a clean, dry jar for months. But for best results, I prefer to use cumin for 3 weeks.
Spiciness - Add max green chillies to make it more spicy. Or substitute 1 tsp of Kashmiri chilli powder with 1 tsp of regular chilli powder.
Fresh chicken stock - Can be added with deglazing the pan. Substitute 1 cup of water with 1 cup of chicken stock.
