2. Many people mistakenly think that dipping wasabi mud in sashimi is for sterilization, but it is not. The reason why the Japanese use it like this is only to better mobilize the original flavor of raw fish. Therefore, when we eat sashimi, never use chopsticks to stir the soy sauce and mustard paste in the small dish, because authentic Japanese think it is impolite to eat like this, and they don't know how to taste sashimi correctly.
When a plate of tuna sashimi is placed in front of us, the first thing that catches our eye is its aesthetic shape, so we should wait until all diners have enjoyed it before using chopsticks to taste it.
4. When eating tuna sashimi, you should first put an empty plate and a small plate with soy sauce in front of you, put a piece of sashimi in the empty plate with chopsticks, then put a proper amount of mustard on the fish fillet, then fold the fish fillet, cover it with mustard, dip it in soy sauce, clip it up and send it to your mouth.
When we chew tuna sashimi for the first time, we can easily taste three flavors, namely, the original flavor of fish, the umami flavor of soy sauce and the taste of wasabi (pungent and pungent). As you keep chewing, the taste of fish will get worse and worse, and you will feel that your mouth is full of saliva. After eating tuna bones, it's best to have another bite of cucumber or shredded radish, or a small piece of ginger, so that you can taste another fish bone.
