1. Cooking: Put mustard pimples in a steamer and cook for 10 to 15 minutes on medium heat. This treatment can help to volatilize the bitter taste of mustard and make it taste better.

2, drowning: wash the mustard knot, put it in hot water and remove it. Soaking the boiled mustard knot in one's heart in cold water for more than half an hour can further remove the bitterness.

3. Add salt: stir the washed and cut mustard bumps evenly with salt and leave them for more than an hour. Squeeze out excess juice, rinse with clear water and fry. This therapy can reduce the bitterness of mustard papules.
