Indian food is varied and spicy. Tuna fish comes from the sea and is very tasty. The fish is first fried before cooking. I like it too. I have never cooked fish with sweet potatoes. Desi potatoes are very tasty. But fish can have a different taste with sweet potatoes. I learned something new. Garlic and ginger enhance the taste of food. Many more spices have been used. After cooking, I feel like I'm eating a little too. Very good cooking skills. A beautiful recipe. I think tuna fish would be much tastier than salmon fish.
