? Mustard is divided into yellow mustard and green mustard, however, these two kinds of mustard is not the same at all, yellow mustard is produced in China, is the seeds of mustard by mixing with water to grind and become, mustard seeds originally did not have a pungent flavor, mixed into the water after the reaction, and produced a pungent and stimulating flavor, mostly used in Chinese gazpacho production. Yellow mustard is bright yellow in color and is also used in traditional Chinese medicine, both internally and externally it has some therapeutic effects, internally it can relieve symptoms such as vomiting and stomach pain, and externally it can treat joint pain. And green mustard from Europe, also known as green mustard, is another plant named wasabi extracted from the seasoning, is light green, in addition to a pungent flavor, but also with a burst of aroma. Another plant that can be made into a mustard-like condiment is horseradish, which is ground up to have a flavor that is more similar to green mustard, but appears yellow.
? ? Wasabi is most often used in Japanese cuisine, but yellow mustard is not used in Japanese restaurants, instead green mustard made from wasabi and a wasabi-like condiment made from horseradish are used. In more upscale Japanese restaurants, green wasabi is used because it has a more pure flavor and tastes better with sashimi, sushi, and other Japanese foods, but most Japanese restaurants, including those in China, use horseradish as a wasabi-like condiment.
There are two reasons for this, one is that horseradish is easier and cheaper to grow than wasabi, and the other is that wasabi is easily dissolved in soy sauce. Many Chinese people like to add some seafood soy sauce to their wasabi, and if you use green wasabi, it will quickly lose its flavor if it is placed in soy sauce, which is not the case with horseradish.
So when you eat Japanese food, don't call all the spicy seasonings wasabi sauce, you can ask the information restaurant staff to identify the use of which is a kind of spicy seasonings, If it is green wasabi, it is recommended not to be eaten with soy sauce, and if it is yellow wasabi, it may be associated with the sashimi and other food not to achieve optimal
It is recommended not to eat with soy sauce if it is green wasabi. When you buy wasabi, you should look at the recipe so that you can choose a better seasoning.
