Add 1/2 teacup water. Using cloth/oven mittens, take the clay pot with both hands and rotate the clay pot gently thereby mixing the fish and masalas well. Using a spoon might break the fish pieces. Allow it to boil.
Cover and cook till done. Rotate the clay pot twice or thrice in between cooking as done in the above step, to avoid the curry from burning.
Transfer to a serving dish and serve along with rice.
Note: When making Mackarel/Vaala fish you can also add Tomato and Drumsticks (cut into pieces) in the step where you add the fish to the claypot. Raw mango pieces can also be added instead of Tomato.
