2. Mustard powder is the main raw material for making mustard, which is generally available in large supermarkets. Many people like to make mustard sauce to taste after buying home, but if the production process is not in place, it will easily lead to only bitterness and no spicy taste.
3. When preparing mustard powder, you should first adjust it with warm water. Remember not to use boiled hot water directly, otherwise it will easily lead to the inactivation of mustard enzyme in mustard powder and the spicy taste will be difficult to stimulate.
4. After mixing, add oil, salt, sugar, vinegar, etc. Put them in turn, stir them evenly, and put them in the shade for fermentation. Wait for 2~3 hours or so, it will have a very pungent taste and will not have a bitter taste.
