How to make the oil residue

Put the pig fat into oil and fry until the fat becomes dry, then remove the oil residue. Chop the oil residue and tofu together, add flour and various seasonings, and cook.

Ingredients ratio: 1; 2; 1

Here in the oil pan and stir-fry the cooked taro (if nothing else, it will definitely break into small pieces), Add water and oil residue, cook until boiling, turn off the heat, season, add starch to thicken the pot, and it’s ready to serve

PS: I tried it on my own and I think it’s pretty good
