Potatoes are easy to obtain and we can use potatoes to make a lot of rich delicacies. Whether it is making potato chips, fries, mashed potatoes, fried potato shreds, etc. No matter what application we use potatoes for, we first need to 去除土豆皮. The potato skin is very thin, with only a thin layer of brown on the surface. If we use a knife to cut the ground, it will cut off a lot of meat.
如何轻松去除土豆皮而不浪费多余的肉？
1. 焯水冷冻以去除土豆皮
首先，用清水洗净土豆表面的泥土，然后用刀在土豆上划一个圈。接着，将土豆放入热水中浸泡一段时间。倒出热水后，放入冷水中浸泡。浸泡几秒钟后，可以看到土豆膨胀并出现划痕。我们可以沿着膨胀的部分轻松去皮。
2. 用锡箔纸擦拭去皮
我们可以将用过的锡箔纸揉成球，然后清洗土豆，用锡箔纸擦拭土豆，去除土豆表面的一层薄皮。这种方法不会伤害到肉质。
3. 使用钢丝球
如果你没有废旧锡箔纸，或者觉得使用锡箔纸有点浪费，那么我建议你使用钢球去皮土豆。具体操作方法是用钢丝球擦拭土豆表面，擦拭后用清水冲洗干净。
4. 使用橡胶手套
冬天，我们用橡胶手套洗菜或洗衣服。一般来说，橡胶手套具有均匀的粗糙度，这样我们可以利用颗粒与土豆相互摩擦，使土豆皮脱落。这种方法可以确保不伤手，并且可以达到去除土豆皮的效果。
We can easily remove potato skins with the above four methods. The first method is to use the principle of thermal expansion and contraction. The skins of the potatoes open when they are soaked in hot water. And it spreads around along the scratches. Using this method can not only achieve the effect of easy peeling but also remove potato starch. The other three methods achieve peeling function by adopting friction between two objects. Commercially, brush peeling machines also use this principle. It is peeled by the opposite rotating friction between the hard brush and the potatoes.
Therefore, if you want to remove potato skins at home, I suggest you use the above four methods; if you want large-volume peeling. I suggest you use a commercial potato peeler.
