How to choose sardines

1. Eyes that don’t lie: Eyes are the easiest to reveal secrets. A fresh fish must have clear, bright, full and lively eyes with prominent eyeballs and clear black and white boundaries. If the fish’s eyeballs are sunken and cloudy, it is better to give up.

2. Aristocratic manner A fresh fish will not be careless about its appearance just because its life ends. The slightly closed but easily opened mouth of the fish shows a peaceful calmness, and the scales on its body are like a carefully worn dress, neat and close to the body, and there is no sloppy falling off. Even if you open the tightly closed gill cover, you can see the bright red and clear gill filaments. Fish with loose scales that are easy to fall off and loose gills cannot bring you delicious enjoyment.

3. Strong backbone Fish do not have a backbone like humans, but a fresh fish, like a person, has a backbone of faith, and will never slack off even after life fades. If you pick up a fish by the head, its body will not bend, and when you stroke its body, you can feel the elastic muscles.

4. Cleanliness You will not see any sticky dirt coming out of its gills or cloaca, and its mouth is also clean. Transparent and smooth mucus is all over its body. Although it has a fishy smell, it is not strong and will not make you feel disgusted. These fresh characteristics are also applicable to frozen fish. Moreover, the cross-section of fresh frozen fish is bright, and the weight after thawing will not change much from before.
