Sushi ginger is sweet, thinly sliced young ginger that has been marinated in a solution of sugar and vinegar. It is a healthy sushi ingredient that helps relieve sinus congestion. Served in a pickled form, it is used to cleanse the palate after each piece of sushi. Sushi ginger contains compounds called gingerols and shogaols, which stimulate digestive juices and neutralise stomach acids, making it beneficial when consuming raw fish. It can also lower cholesterol levels and limit blood clots in a similar way to aspirin.
