How to make canned sardines at home

raw material:
500 grams of sardines (very cheap, frozen, about 4 yuan per pound), 100 grams of tomato paste,
Ingredients: salt, cooking wine (or rice wine), a little soybean oil, just enough water to cover the fish body.
practice:
1. Pour a small amount of soybean oil into the pot, put the cleaned sardines in and stir-fry for a while, then pour in the cooking wine, add tomato paste, salt and water and bring to a boil.
2. It is best to put it in a pressure cooker for cooking (you can also use a purple clay pot as a last resort).
Effect (if the preparation is successful): The skin of the prepared sardines will be golden and crispy. When you bite it, you will find that the fish meat inside is thin, tender and tastes great.
