There are many ways to do pork belly. We prepare pork belly first, then wash it and blanch it with hot water, and add ginger slices and onion segments to effectively remove the fishy smell. Then we take out the cooked pork belly, drain the water, cut it into thin slices, heat the oil in a pot, stir-fry the onion, ginger and garlic until fragrant, then add a tablespoon of red oil bean paste and stir well.
