Mustard is the crushed powder of mustard seeds, and the one with high oil content and spicy taste is better. It is used for dressing vegetables and is a seasoning for appetizing and understanding. There are several ways to adjust the spicy mustard:

1. Mix mustard with water, put it in the stove, put it in a cage and steam it for a while, and the spicy taste will come out.

2. When the mustard is mixed, mix it with boiling water, cover it, and let it stand in the shade for a few hours, which can also give it a spicy taste.

3. After the mustard is washed with boiling water, it is slightly cold. Punch a few holes with chopsticks, pour some boiling water on it until the mustard has not passed, then put it next to the stove, cover it for about 6-8 hours, and then pour off the boiling water on the floating surface. This method will not only have a strong spicy taste, but also remove all the bitterness.

The prepared mustard can be eaten immediately. If you can add some sugar and sesame oil and mix well, it will taste better. In western food, vinegar essence (white vinegar), refined salt, white sugar, vegetable oil and white pepper are added to the prepared mustard, and then they are stirred vigorously, covered in the refrigerator and chilled, which makes it a "little mustard" with a unique flavor.
