2. Asparagus is the tender stem of Asparagus. Its meat is very tender and easy to cook. Just boil it in water for 2-3 minutes. If it is cooked for too long, the asparagus will be too soft. The eating taste will become worse, which is not conducive to subsequent cooking; if the cooking time is too short, the asparagus will not be fully blanched, and the oxalic acid component will not be precipitated.
