Ingredients: eggs? Shrimp? Ham? Asparagus (these four are the oldest, what else do you want to put depends on your preference. )
Practice: steamed rice with a little sushi vinegar (slightly hard). After steaming, put salt according to your own taste. Then put the seaweed on the sushi curtain, put the rice on it, put the ingredients neatly (the ingredients are placed at 1/3 of the seaweed) and start to roll up. Roll into a barrel. Just cut it into small pieces with a knife when eating.
Sauce: You can use Japanese soy sauce or Japanese green mustard directly.
