1 lb boneless white fish pieces (Trevally/Jack/Parai meen/Pomfret (Sauvik's favorite)/whatever)
Oil for pan frying

Marinade:
Curd / Thick Yogurt - 1 cup
Chilli powder - 1 tsp or to taste
Garam Masala powder - 1 tsp
Pepper Powder - 1 tsp
Ginger Garlic Paste - 1 tbsp
Salt to taste
Lemon Juice - 2 tbsp
Coriander leaves - 3 tbsp finely chopped
Mint leaves - 3 tbsp finely chopped
Corn Starch - 3 tbsp
Oil - 1 tbsp

Mix the marinade ingredients, add fish, marinate at least 30 minutes.

Put the fish pieces on skewers, pan fry, rotating until cooked, about 15 minutes. Or oven cook at 450F in a foil lined baking tray for 10-15 minutes, flipping skewers halfway through. Skewering isn't really even necessary.

Remove from the heat and serve hot with some lemon wedges.
