How to microwave cook walnut kernels and peel them

Walnut kernels can be roasted and peeled in a microwave oven, but the heat and time should be controlled during operation to avoid burning.

Walnut kernels need to be cleaned and dried before being placed in the microwave oven. They should be spread flat in a specialized container for the microwave oven, with a thickness not exceeding two layers. Heat on medium high heat for 1 minute, then remove and flip, observe the color change, repeat heating for 30 seconds until slightly yellow and fragrant. During the heating process, walnut kernels will release oil, which helps to separate the film. Wrap and rub them with kitchen paper while they are still hot to easily remove the skin. The walnut kernels heated by microwave have a crispy texture, but it is important to avoid prolonged heating to prevent bitterness. If using shelled walnuts, it is necessary to first crack the gaps and then microwave heat them. The steam inside the shell will cause the walnut kernels to separate from the inner wall. Some varieties of walnuts have thicker skin, which can be heated and soaked in cold water for 2 minutes to assist in peeling using the principle of thermal expansion and contraction. The difference in microwave power may lead to uneven heating. It is recommended to heat in batches for short periods of time and check the status each time. The peeled walnut kernels should be sealed and stored to prevent oxidation and spoilage. Walnut kernels are rich in unsaturated fatty acids and vitamin E, and moderate consumption can help promote cardiovascular and cerebrovascular health. It is recommended to control the daily intake within 20 grams to avoid gastrointestinal discomfort caused by excessive consumption. Although microwave heating is convenient, traditional ovens or stir frying can better preserve flavor, and different methods can be chosen according to needs. When storing walnut kernels, they should be kept away from light and moisture, and can be refrigerated to extend their shelf life. People who are allergic to nuts should avoid consumption, and children should be supervised by their parents to prevent coughing.
