Put the mutton in cold water, add onion, ginger and cooking wine until it boils, take it out and rinse it with clear water for later use.
Boil a pot of water again, put the mutton in it, then add the onion, ginger and pepper, and you can stew it.
Boil with high fire first, and then simmer with low fire 1 hour. Then, we add some salt and pepper, continue to stew for about 10 minutes, and then turn off the fire and take it out.
