When many people make yellow mustard at home, they often find that it tastes only bitter, but not spicy. This is basically because the spicy flavor is not fully stimulated during the preparation. There is no way to remedy it, so they can only make it again.
The correct preparation method of yellow mustard sauce is to first take an appropriate amount of yellow mustard powder and put it in a bowl, and then add warm water to open it. Pay attention not to use hot water here, otherwise it will lead to the loss of mustard enzyme activity and it is difficult to stimulate the spicy taste.
