2. blanching asparagus before frying can not only shorten the heating time in the cooking process, but also reduce the loss of vitamins and heat-labile nutrients in asparagus, making the fried asparagus more colorful and crisp.
3. First add enough water to the pot, then add a small amount of salt, drop a few drops of sesame oil in the pot, turn on a big fire to boil the water, and then pour the washed asparagus into the water. We must pay attention to controlling the blanching time here, otherwise the asparagus will be too soft and old, and the taste will be bad, which will also cause nutrient loss.
4. The cut asparagus can be taken out after blanching for 3 minutes. If asparagus is a whole pot, it will take a little longer to blanch, and it will take at least 7-8 minutes to break. Asparagus will lose water-soluble nutrients when it is blanched, so it can't be blanched for too long. As mentioned earlier, adding some salt in the blanching is because it can effectively reduce the loss of nutrients.
Therefore, before frying asparagus, you must blanch it first, and pay attention to the way of blanching. You should add salt and sesame oil to the water to reduce the loss of nutrients and control the blanching time, so that the treated asparagus will not be bitter when used for cooking, and it will keep the asparagus green.
