Sushi is a traditional Japanese food. Its main ingredients are rice, fish, seafood and some vegetables. If it is stored at room temperature, it is not recommended to eat it overnight, because vegetables may produce nitrite overnight, and seafood is rich in protein, which is also easy to breed bacteria and lead to spoilage. Sushi can still be eaten overnight if it is sealed and refrigerated in the refrigerator. The low temperature in the refrigerator can inhibit the growth and reproduction of bacteria. Although the taste will be worse, it can still be eaten.

Sushi can be heated or not after being put into the refrigerator. In general, sushi does not need to be heated, because it may destroy its original flavor. However, if sushi hardens in the refrigerator, it will not taste good if it is too hard. At this time, it is enough to heat the sushi a little, but the heating time should not be too long.

If the sushi is too hard overnight, you can directly heat it in the microwave oven, usually for about a minute. If there is no microwave oven, you can also put sushi in a cooked rice cooker and stew it directly for one minute.

Brief introduction of sushi

The earliest sushi in Japan is a small food made of rice, raw fish and sauce that can be eaten in one bite. There are many kinds of sushi now, which can hold many things, but you must eat it all at once. Japanese sushi has been recorded in heian period Code "Yan Xi Style", which was completed in 927 AD. Sushi at that time was a way to preserve fish.

Rub the salt on the fish, press it with a heavy object and let it ferment naturally. You can eat it when it is sour. It's delicious, but it's a bit like stinky tofu in China. It smells terrible, but it tastes good. This method originated in Japan. But this method is time-consuming and laborious, and soon developed into a simple way to soak fish in vinegar. Developed sushi refers to any food with other fillings added to vinegar-mixed rice.

The popular sushi in Japan includes "roll" and "box sushi" in addition to "grab" (that is, sushi that we often eat in the street). "Roll" is to wrap rice, cucumber, tuna, eggs and pickled radish with seaweed and divide them into large rolls and thin rolls, that is, the size. Usually, a sushi roll is 90 grams of rice and boiled about 200 grams. Eat it wrapped in seaweed.

Sometimes thin scrambled egg skins can be used instead of laver. A sushi roll wrapped with a whole piece of seaweed is called a "too roll" (that is, a thick roll), and a sushi roll wrapped with only half a piece is called a "thin roll". Sushi rolls usually contain boiled sweet and cold weather, cucumbers, sausages, mushrooms, scrambled egg skins, fish floss or duck celery.
