1. Carp cramps:

　　鲤鱼的两侧皮下像一根白色的肌腱，在烹调之前把它捞出来，因为它不仅鱼的气味很重，而且是一根粗壮的毛，也就是说，毛，不适合一些病人食用。画白色肌肉时，应在鳃和尾巴处约1英寸处，刀到脊柱为止;然后用刀从尾部到头部平拍，使鳃后刀刃内肌腱头取出，用指尖捏住肌腱头拔出肌腱;然后用同样的方法从另一侧取出白色肌腱。

　　The carp has a white tendon on both sides of the skin, which is pulled out before cooking because it not only smells heavy, but also has a strong hair, that is to say, hair, which is not suitable for some patients to eat. When drawing white muscles, it should be about 1 inch at the gill and tail, until the knife reaches the spine; then, flat pat with the knife from the tail to the head, so that the tendon head in the blade of the back knife of the gill is removed, and the tendon head is pulled out by pinching the tendon head with the fingertip; and then the white tendon is removed from the other side by the same method.

　　2. 河鱼和湖鱼

　　2. River fish and lake fish

　　河鱼因为它生活在清澈流动的流水中，所以鳞片薄，灰色，光泽明亮;这食物很好吃，有点甜。湖鱼因为它生活在一个非常厚的淤泥中，在平静的湖水中，所以鳞片是厚的，黑色的灰色，煮过的菜，吃的时候有很强的泥味。

　　River fish is thin, gray and shiny because it lives in clear flowing water; the food is delicious and a little sweet. Lake fish because it lives in a very thick mud, in the calm lake water, so the scales are thick, black gray, cooked vegetables, eat when there is a strong muddy taste.

　　3.去除苦味:

　　3. Remove bitterness:

　　当你杀了一条鱼，如果你摸一下胆囊，鱼的味道会很苦，很难吃。不仅如此，鱼胆汁不仅有苦味，而且有毒性，高温烹调也不会苦味和毒性。然而，胆汁可以与葡萄酒、小苏打或泡打粉溶解。因此，用葡萄酒、小苏打或泡打粉将胆汁涂抹在鱼身上，用冷水冲洗以去除鱼的苦味。

　　When you kill a fish, if you touch the gallbladder, it tastes bitter and tastes terrible. Moreover, fish bile is not only bitter, but also toxic. Cooking at high temperature will not eliminate bitterness and toxicity. However, bile can be dissolved with wine, baking soda or baking powder. Therefore, the bile is smeared on the fish with wine, baking soda or baking powder, and rinsed with cold water to remove the bitterness of the fish.
