Misgurnus anguillicaudatus must be eviscerated, and the viscera will always be dirty. If you don't eviscerate Misgurnus anguillicaudatus, it will affect the mood of eating Misgurnus anguillicaudatus once it is cooked!
It's a bit difficult to remove the internal organs of the loach. I'll tell you what to do. Use a thin wire, make a small hook at one end and a small circle at the other end, put a small trap on your finger, the length is six or seven centimeters, remove the head of the loach, put the hooked wire into the belly of the loach, and then gently pull it out, and all the internal organs of the loach will be hooked out. Then wash the loach with water and it will be clean.
it's no good soaking loach in salt water. Loach can only spit out a little dirty water, but its internal organs can't. Besides, soaking in salt water will soak all the mucous membranes on loach's skin, which is the most nutritious, fragrant and tasty!
scalding Misgurnus anguillicaudatus with boiling water is also the biggest mistake, and it will also burn the most nutritious mucosa on Misgurnus anguillicaudatus skin. Without that mucosa, not only the nutrition of Misgurnus anguillicaudatus, but also its fragrance and taste will be lost!
