Home made sweet and sour pork ingredients:800 grams of pork ribs, ginger, green onion knots, peppercorns, star anise, cooking wine. Seasoning:a little salt, light soy sauce, dark soy sauce, rock sugar, aged vinegar, water or golden ratio juice:1: 2: 3: 4, that is, 1 spoon of cooking wine, 2 spoons of soy sauce, 3 spoons of sugar, 4 spoons of vinegar. Exercise:1. Blanch the ribs in a pot of cold water, add the cooking wine, peppercorns, star anise and scallion knots, bring the ginger to a boil over high heat, turn to medium heat and simmer for 15 minutes, then remove from the pot.2. Pour a little oil into the pot, add the rock sugar and simmer over low heat until it melts.3. When the color is amber, stir-fry the ribs to coat them evenly.4. Add the boiling water along the edges of the pot. Be sure to bring to a boil. Then add 2 tablespoons of soy sauce, ? tablespoon of dark soy sauce, 3 tablespoons of vinegar (reserve a little before starting the pot), and 3 rock sugars. Bring to a boil and simmer on low heat for 20-30 minutes. (Note: the amount of rock sugar here is reduced because a large portion of it is used in the stir-frying of the sugar color, so the amount of sugar used here is less. If you don't stir-fry the sugar color, just put it according to the normal proportion.) If you are not sure, you can use the golden ratio to mix a bowl of sweet and sour sauce, to ensure that you will not go wrong, will certainly fail. Empty bowl:1 tbsp cooking wine, 2 tbsp soy sauce (I used 1.5 tbsp light soy sauce, 0.5 tbsp dark soy sauce, or 1 tbsp dark soy sauce and 1 tbsp red soy sauce), 3 tbsp sugar, 4 tbsp vinegar (preferably rice vinegar), and water. This ratio should also be adjusted according to the amount of ribs. If you can't master it, you can taste the sweet and sour before adjusting.5. Finally, add a little salt to season the juice, sprinkle with white sesame seeds, drizzle with a little vinegar, stir to mix evenly out of the pot.
