It's not so much a speculation but a lot of material, the steps are very simple.
The fire burned the pot.
Pour the oil, add the ginger, garlic, and a few bursts after the oil is hot. (I didn't put the garlic out of my house)
Pour a few drops into the washed pig tongue.
Add water, soy sauce, Fujian old wine, salt, sugar, chicken, stir fry a few times. Cover the lid and cook. (If you put more water, then the soup is not cooked, don't know how to know.)
When the soup is left a little, open the fire and collect the juice.
Is it super simple?
