1, the peel of asparagus is not necessary. If it is fresh and light green asparagus, you don't need to scrape it. Only the old asparagus needs to scrape it, because the skin of the old asparagus is tough. Just peel it off from the root.

2. The best way to peel old asparagus is to tear it faster by hand. Pick up asparagus in the left and right direction with both hands, tear off a small layer of skin from the root and fold it down gently. Asparagus will naturally break at the junction of old and tender, and the broken part does not need to be removed, indicating that this part is still tender.

3. When frying asparagus, remember to blanch it in boiling water 1 min. Add 1 teaspoon salt and put it in boiling water to prevent asparagus from turning yellow. After frying, the asparagus is still as green as new.
