The biggest difference is that one is salty and the other is sweet. Prepare ingredients. After cleaning the ribs, put them into the pot, pour in cold water and a spoonful of onion and ginger cooking wine, and turn off the fire after the dirty dog comes out of the water. Rinse the ribs with warm water. Dry the blanched ribs with kitchen paper. Fry the ribs in a little oil until golden brown. Add a spoonful of onion spice wine. Add two spoonfuls of soy sauce Add two spoonfuls of tomato sauce. Add three spoonfuls of rose rice vinegar. Stir the sauce and ribs evenly and stir-fry for a while. Add water to the ribs, bring to a boil and stew for about 20 minutes. When half of the soup is left, add a handful of sugar to the ribs, stir well, scoop a little sauce with a small spoon to taste the sweetness and sourness, and continue to cover the stew when the sweetness and sourness are suitable. When the soup is about one third left, you can fire and collect the juice.
