Hazırlanışı
1Grind the pork belly using a meat grinder if you have one, or chop well with a chef’s knife (do not use a food processor, which will turn the meat into a paste). Combine in a large bowl with the ground pork and refrigerate.
2To make the sprouts, combine the mustard powder, water, soy sauce, vinegar, and sugar in a bowl, mix well, and set aside.
3In a pot over high heat, bring 4 cups water and the salt to a boil. Add the bean sprouts. Remove from the heat when the water returns to a boil and the sprouts have floated to the surface. Drain through a fine-mesh strainer and combine with the mustard sauce. Set aside.
