How to make sweet and sour pork ribs (tomato sauce version)? First, prepare a pot of water to boil, cut the ribs into small pieces as much as possible, wash them, boil the ribs, ginger slices and cooking wine for five minutes after the water boils, and drain the water; Mix the eggs for later use; Put flour, starch and salt into the ribs, then mix the eggs and pour them into half of the ribs, stir well to see if the ribs and starch can be fully mixed, then add the egg liquid as appropriate, and finally dip each rib; Put more oil in the cold pot and fry the ribs. When it is 60% hot, turn the heat down and put down the ribs one by one. It is best to use chopsticks to avoid sticking together. Turn it in the middle from time to time. It takes about ten minutes to fry the ribs, and both sides are yellow. Take the pot away for later use. Leave a little oil in the pot, still simmer, add tomato sauce and sugar, stir-fry twice to taste, add sugar when it is sour, add white vinegar when it is sweet, and add half a bowl of water (one bowl to eat) for half a minute if it tastes like it; Or simmer slowly, first pour in half of the water starch (starch mixed with water, stir it when using), stir it quickly and evenly to see how thick it is, a little thinner than yogurt. Pour in the ribs and stir well. Sprinkle with white sesame seeds or black sesame seeds and serve (forget to put sesame seeds). If you don't put sesame seeds, you can decorate them with shredded onions.
