Notes on eating sushi:

1. Use your hands instead of chopsticks: Traditional diners eat sushi with their hands instead of chopsticks. Diners can use chopsticks to eat, or they can eat directly with their hands. Using chopsticks can easily break the shape of the sushi, but if you hold it with your hands, the taste of the sushi will be affected by the temperature of your hands. Both have their own pros and cons. Generally speaking, Hand holding is more traditional and widely recognized.

2. Dipping sauce: Most nigirizushi does not need to be dipped in horseradish (wasabi). The flavorful nigirizushi chef has already brushed the sauce on it, and does not even need to be dipped in soy sauce.

3. Eating order: Sushi should be tasted in order from light to rich. Start with light white fish, then move on to rich and shiny fish, then move on to red fish, salmon, and caviar, and finally taste the strongest flavors of various shellfish, oysters, abalone, sweet eels, and sweet shrimps Sushi and roll sushi made with ingredients such as , fish roe, sea urchin, and thick egg rolls.
