1, First of all, we need to make mustard powder into a paste with warm water, and add a proper amount of white vinegar to adjust its pH value to between five and six, and then put mustard paste into a pot and steam it for a period of time. Then, mustard paste, dissolved thickener, salt and white sugar are mixed together and disinfected.

2. When preparing mustard sauce, if the mustard powder we buy is coarse in texture, we need to use tools to make the mustard powder finer first, and then we can add twice as much warm water to the mustard powder and make it into a paste.

3. You can also add a little white vinegar to the mustard paste and adjust the pH value of the mustard paste between five and six. Then the mustard paste is sealed and steamed in a steamer for a period of time, and kept at a certain temperature for two or three hours.
