Before starting to process tuna, it is important to recognize the various types of tuna available in the market. Some types of tuna sold in the market include imported frozen tuna with pink color, and local tuna with colors ranging from white to dark. Tuna cakalang with yellow fins is a good choice because its fishy smell tends to be lower compared to other types.

Choosing fresh tuna is the most important step. Fresh fish has a fresh sea aroma and its meat is tender. Other characteristics of fresh fish are clear eyes, fresh red gills, and moist skin. Avoid fish with a pungent smell, slimy texture, and dull color. Buying a whole fish also makes it easier for us to assess its freshness.

Cleaning the tuna fish carefully is the next step. Remove all the inner parts of the fish and rinse it thoroughly with running water. For better results, soak the fish in ice water for a few minutes. The ice water can help firm up the fish meat and reduce the fishy odor. Fresh and clean fish will have a significant impact on the deliciousness of the dish later on.

One effective kitchen ingredient to eliminate the fishy smell in tuna is salt. Sprinkle salt on the entire surface of the tuna and gently rub it evenly. Let it sit for a few minutes before cooking. Salt not only helps to remove the fishy smell but also enhances the flavor of the fish.

Lime or lemon is a natural ingredient known to be effective in removing fishy odor from fish. Coat the tuna fish evenly with lime or lemon juice and let it sit for 10-15 minutes. Rinse with clean water before cooking to avoid excessive sour taste. The use of lime or lemon also adds freshness to the fish.

Ginger is another natural ingredient that is effective in overcoming the fishy smell in tuna. The aroma of ginger will make the fish more fragrant and also enhance the taste. Thinly slice the ginger, then rub it evenly on the fish. Soak it in water for a few minutes before starting to process the tuna according to your preference.
