You don't have to shave off the silvery white body of hairtail. It is equivalent to a thin layer of oil on hairtail. And this silvery white layer is also nutritious. As mentioned above, the silvery white layer of hairtail can also tell whether hairtail is fresh or not. If it is not fresh, hairtail will be secretly colored.

Moreover, when frying in a pot, hairtail will stick to the pot well without this layer of silvery white hairtail, so hairtail is not a whole piece, but broken.

The bought hairtail should be cleaned immediately. Soak hairtail in water at 80℃ for about ten seconds, then immediately put it in cold water, and scrub the scales on the surface of hairtail with a brush or cloth. When cleaning, you can add some onions and ginger, which can remove the odor without affecting the deliciousness of hairtail.

Matters needing attention in treatment of silver substance on hairtail surface

1, don't soak in hot water

The silver grease on the surface of hairtail will melt when it meets 75℃ hot water, so be careful not to soak it in hot water above 75℃ when cleaning hairtail to avoid nutrient loss.

2, can't scrape with a knife

Many people scrape off the scales with a knife when cleaning fish, but hairtail doesn't need to scrape off silver and phosphorus deliberately. It is best to keep this layer of silver grease as much as possible, which will be more nutritious.

3. Yellow silver grease should be removed.

The silver grease on the surface of hairtail will deteriorate and turn yellow when exposed to air for a long time. Therefore, when the silver grease on the surface of hairtail turns Huang Shi, it must be scraped clean before eating. If hairtail still smells at this time, it means it has gone bad and can't be eaten any more.
