I think the practice is as follows:

1, pork ribs cut off the head and tail, cut from the bone seam, cut into segments.

2, ginger slices, scallions cut into segments, pot with cool water to put the ribs.

3, add wine to dispel fishy, blanch for two minutes, fish out and wash.

4, pot with cooking oil, put onion, ginger, pepper, star anise, sautéed with rock sugar.

5, sugar stir fry until slightly yellow put ribs, stir fry and add vinegar, soy sauce, water over ribs.

6, add salt for seasoning, soy sauce coloring, simmer for forty minutes after the fire juice can be.
