Sardines are rich in omega-3 fatty acids, which are essential nutrients for human body. Because the human body cannot synthesize omega-3 fatty acids, it is particularly important to take them from food. Omega-3 fatty acids can not only benefit the human brain, but also reduce the risk of heart disease. Most supermarkets sell canned sardines, but many people still have a soft spot for fresh sardines. There are many ways to cook sardines, you can choose according to your own preferences.

Method 1: Preparation before cooking

1, buy fresh sardines from supermarkets or food markets. Buy whole sardines without peculiar smell. Don't buy sardines that have been silted up, but choose the freshest ones.

Don't buy old fish. Older fish intestines will slowly flow out of their stomachs, so they are also called "heartbroken fish".

2. Scale in cold running water. When picking up sardines, you need to scrape off all the scales outside. Scrape the fish back and forth with your fingers under the tap water and scrape the scales clean.

3. Hold the fish belly up in your hand and remove the internal organs. When doing this step, first cut off the whole belly of the fish with a fish knife, and then remove the internal organs.

4. Boning. Cut the meat on both sides along the spine with a fish knife.

Insert the knife under the ribs, slowly and deeply, and finally separate the fish from the spine.

Cut the spine where it meets the head and tail with sharp scissors.

Pinch the spine with your forefinger and thumb and pull it out. When extracting bones, you should start from the tail of the fish, move slowly to the head, and finally extract the whole spine.

5. Wash the fish with lemon juice. Before cooking, you can also add some seasonings, such as salt and pepper.
