The simplest and easiest way to eat green walnuts is to put all green walnuts in a plastic bag, tie their mouths tightly and leave them for two or three days. At this time, although the green skin outside the walnut remains unchanged, the green skin inside has been separated from the hard shell of the walnut. At this time, as long as the green husk is cut with a knife, it is easy to separate the green husk from the hard shell of walnut, or gently clamp it with a walnut clip. This method is the most environmentally friendly and the simplest. The walnut shell without green skin is very light color, and the skin of the walnut kernel inside is also very light color, while the walnut directly peeled on the market last year is particularly dark inside and outside. I think it may be something. Therefore, it is the most environmentally friendly and safest to go to the green husk by yourself. Just cover it for two or three days. Don't cover it for too long.
