Take a kadhai/pan, add the oil and heat it. To the hot oil add the fish head and fry them properly till the raw smell is gone. Remove the fish head and keep them aside.

Add more oil if required. To the same oil add whole cumin, bay leaves, elaichi, cinnamon stick and fry for a minute till you get the aroma of the spices. Now, add the sliced onions and fry till they become translucent and slightly golden.

Add the turmeric powder, cumin powder, red chilli powder and salt. Add the ginger, garlic paste, green chilies and tomatoes. Stir till the raw smell of tomatoes goes away.

Now, add the soaked rice and stir for 1 minute. Stir till oil comes out of the mixture. Now, add about 2 cups of water and also add the fried potatoes and cauliflower.

Meanwhile, break the fish head into small pieces and add the pieces at this point. Continue cooking till the rice and veggies are cooked properly.
