Mustard is the crushed powder of mustard seeds, which has high oil content and spicy taste. Used for seasoning vegetables, it is an appetizing and understanding seasoning. There are several ways to adjust spicy mustard:

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

2. After 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 make it spicy.

3. Wash the mustard with boiling water and let it cool slightly. Punch a few holes with chopsticks, pour some boiling water on it until the mustard doesn't pass, then put it next to the stove, cover it for about 6-8 hours, and then pour out the boiling water floating on the water. 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 add some sugar and sesame oil and mix well, it will taste better. In western food, vinegar essence (white vinegar), refined salt, sugar, vegetable oil and white pepper are added to the prepared mustard, and then it is stirred vigorously and covered in the refrigerator for cold storage, which becomes a "small mustard" with unique flavor.
