How to open the shell of walnuts is the easiest

The simplest way to open a walnut shell is to use a walnut clip or hammer to strike it. The walnut shell is hard and difficult to break open by hand. With the help of tools, the kernels can be quickly and completely removed, mainly through methods such as hot water soaking, oven heating, door gap squeezing, tool tapping, and freezing cracking.

1. Hot water soaking method

Soak walnuts in boiling water for 5-10 minutes. High temperature will soften the wood fibers of walnut shells. Take it out and wrap it with a towel while it's hot. Gently tap the edges to crack it open. This method can keep the nuts intact, but attention should be paid to preventing burns. Soaking for too long may cause the nuts to absorb water and become soft.

2. Oven heating method

Lay walnuts flat on a baking tray and bake at 150 ℃ for 8-10 minutes. After being heated, the air inside the shell expands and creates gaps. After taking it out and cooling it slightly, it can be opened by hand. High temperatures can stimulate the aroma of walnuts, but strict time control is necessary as excessive baking can lead to oxidation and deterioration of the oil.

3. Door Gap Squeezing Method

Place the walnut vertically at the hinge of the door frame and slowly close the door to apply pressure. The wedge-shaped structure of the door gap can evenly spread the outer shell, making it suitable for emergency use without specialized tools. Control the force during operation to avoid crushing the nuts or damaging the door frame.

4. Tool tapping method

Use a walnut clip to fix the waist of the walnut, rotate the handle to apply pressure until the shell ruptures. You can also place walnuts on a hard board and lightly tap the sewing line with a hammer. Tools can accurately control the force, but attention should be paid to the angle of impact, as oblique force can easily cause the nuts to break.

5. Freeze cracking method

After sealing the walnut, freeze it for 2 hours. Low temperature causes different shrinkage rates between the shell and the kernel, resulting in gaps. After removal, it can be separated by tapping lightly, and freezing can also delay the rancidity of walnut oil. However, prolonged freezing time can cause the nuts to dehydrate and harden, affecting their crispy texture.

It is recommended to store walnuts with shells for daily consumption. Eating them now can maximize the retention of nutrients. The opened walnut kernels should be sealed and stored away from light to prevent oxidation of unsaturated fatty acids. The recommended daily intake is 20-30 grams, which can be combined with dark vegetables and fruits to promote the absorption of vitamin E. Special people, such as indigestion, can grind walnuts into powder and add it to Congee, which not only reduces the gastrointestinal burden but also facilitates nutrition absorption. Walnuts stored for a long time should be regularly checked for their Halal flavor to avoid consuming spoiled nuts.
