I didn’t buy sardines in the farm. I watched the squid also very fresh, so I’ll do it with squid today.
Sliced onions, ginger slices, garlic peeled
Add the sugar, vinegar, soy sauce and salt to the tomato sauce. (When mixing, taste the taste and adjust your favorite sweetness)
The squid goes to the end to go to the internal organs, wash it, fry it with oil on both sides, fry it, put it in the pressure cooker, add the seasonings of 1 and 2, then add water (not too much water, how much soup you need at the end) How much water is added, the soup will be thicker).
The pressure cooker chooses the gluten button, and after 35 minutes, the delicious sardines in the tomato sauce will be ready.
