How to remove the fishy smell from the oil of fried fish?

First of all, before frying the fish, cut the onion, slice the ginger, orange peel and pepper in moderation! Generally, dried tangerine peel is the amount of peeling two oranges, and a large number of peppers can be used!

First, fry fish normally. Don't turn off the heat after frying. Take the oil residue out of the pot and put it into the sliced onion and ginger prepared in advance. Don't use a big fire when frying, use a small fire and let the oil fry slowly. The deeper you fry, the better. The purpose of this is to stir-fry the taste of onion and ginger!

Stir-fried to a certain extent, the onion section will be enlarged first, and then the onion section will be fished out first. Add dried tangerine peel and pepper at this time, because dried tangerine peel and pepper are not as heat-resistant as onions and ginger, so add them later. When pepper and dried tangerine peel are fried until crisp and black, they can be taken out together with ginger slices. This fishy oil will turn fragrant again, even if it is cooking or mixing vegetables, it is no problem!

Second, the onion fishy method

If the material used in the first method is too complicated, only onions can be used, and the fishy smell in the oil can also be well removed. Let's talk about specific methods.

First of all, the approximate ratio of onion to oil is 1: 1, where the ratio refers to the weight, for example, 500 grams of oil, just use 500 grams of onion! Then peel the onion and shred it for later use. Similarly, after the fish is fried, remove the oil residue from the pan, then turn the heat down and add the chopped green onion until it is crispy.

The reason why only onions can turn fishy smell oil into sesame oil is mainly because fish contains trimethylamine, which is the main source of fishy smell and melts into the oil when fried! Onion contains a lot of volatile substances, such as allicin, mercaptan and trisulfide. Therefore, by frying onions, the volatile substances in onions can effectively absorb the fishy smell in oil, thus transforming the fishy oil into sesame oil, which is the main principle of removing the smell of onion oil. Note: the amount of onion should not be less than 1: 1, otherwise the flavor will not be enhanced.
