The specific steps are as follows:
1, first draw a circle in the middle of the green walnut with a knife, as shown below.
2. Then draw the fresh green walnut vertically with a knife.
3. If you touch it gently with a knife, half the walnut skin will fall off.
4. Take off the remaining half of the walnut skin and watch it for a while. All the walnuts are peeled.
Matters needing attention
When opening the skin, you must open it from the pre-opened gap to prevent the knife from slipping on the walnut skin and hurting your hand.
