2. Authentic sushi can have sour, sweet, bitter, spicy, salty and other flavors. Therefore, when eating sushi, we should match the seasoning according to the type of sushi. For example, when eating sushi rolls, because there are sashimi and fresh shrimp in the stuffing, you need to dip in thick soy sauce and apply a proper amount of green mustard; When eating sushi, it is best not to dip in soy sauce, so as to eat its original flavor. In addition to thick soy sauce and green mustard, sushi has a more important seasoning, vinegar and ginger. Eating sushi with a slice of vinegar ginger not only helps to add flavor, but also makes sushi more fresh and delicious.
