Perch roe can't be peeled. If the film on the surface is removed, the roe will disperse into water drops after entering the pot. If the perch is braised, the whole roe will be put in a few minutes before the perch is cooked. It has long been easy to boil. You can also dry the whole bass roe, and the color will turn into purplish red. Cutting it into pieces to make soup has a special taste.
