I know how to do a simple operation. The teacher taught us when we were in school.

Go to a large supermarket and buy a bag of seaweed. You can see clearly that you want the kind with a smooth surface, page by page, and it costs about 20 yuan. Then go to the grocery store or other places to buy small mats, which can be rolled. Just a little small will do. Then go to the vegetable market to buy raw materials: cucumbers, radishes, spinach, and ham sausage. These will do. In fact, you can freely play with the tundish, according to personal taste.

The next step is to cook the rice. If you like sesame seeds, you can put some sesame seeds on the rice, and then add sesame oil. Don’t make it spicy. Then use a spatula to mix the rice and condiments evenly. Furthermore, cut the cucumbers you bought into columns, cut the radishes into columns, and ham. Place the spinach in a pot and cover with hot water. Find another bowl and put water in it, and drop some sesame oil on the water. Ready.

After letting it go, start wrapping it. After cleaning the mat, place it under it. Put a piece of seaweed on it. Dip your hands into water and apply it on both sides of the seaweed. The water is the sesame oil you just prepared and dripped with it. Take the rice and spread it flat on the seaweed. Put the radish, cucumber, ham and spinach on the rice. Start rolling it with a mat, preferably tightly, until the seaweed is rolled into a columnar shape. Then cut the rolled seaweed into sections and make them as long or short as you like. Just figure it out. That's it. At that time we called it kimbap, but I don’t know if it’s also called sushi, haha.
