2. There are several ways to adjust mustard powder. You can pour the mustard powder you just bought into a bowl, then mix it with warm water and steam it in a steamer for a while, so that the spicy taste inside will be aroused, or you can directly add boiling water while mixing, cover it and leave it in the shade for a few hours.
3. If you are afraid of bitterness, you can wash mustard powder with boiling water. When it cools down a little, poke a few holes with chopsticks, then pour some boiling water to ensure that the mustard doesn't pass, then put it next to the stove, cover it and pour out the water for about 6 hours. You can also add some sugar, sesame oil and so on after blending. The taste will be smoother.
