Add vinegar powder (dry powder) or sushi vinegar (liquid) to hot rice, and cook after cooling. You can't cook it hot, it will burn the laver skin. When wrapping laver, burn it on the fire first. Laver will be crisp and delicious!

After cooking, put it in a warm place and stir it with sushi vinegar, then spread it on roasted seaweed or seaweed to put other dishes. If the rice is too hot, laver will immediately become soft and even wrinkled, thus becoming unpalatable. If the rice is completely cold, the rice grains will become hard and unpalatable.

Extended data

Sushi actually means salted fish. In ancient Japan, "すし" was written, which means salted fish, and "sushi" is also the pronunciation of ""in Japanese.

In ancient Japan, sushi was salted fish marinated with salt and rice, which was very disgusting, because it was difficult to preserve the food at that time, so it was necessary to make sushi, but it was only an emergency food when going out or marching in war, not an elegant thing. The reason why the Japanese want to write salted fish as "sushi" is also because "salted fish" is indecent. In order to beautify and not remind people of salted fish, write "sushi".
