Youdunzi is usually opened at the entrance of the alley in the afternoon, with a coal stove and a small iron pot on it. A pot of thin batter and a large pot of shredded radish mixed with chopped green onion. The seller of You Dunzi scoops a spoonful of batter, pours it into an oval iron mold and shakes it well, then adds chopped green onion and shredded radish, then scoops a spoonful of batter and spreads it on top of the shredded radish, and then frys it in a frying pan. This kind of delicious and inexpensive food is crispy on the outside and tender on the inside, oily but not greasy, and everyone loves it. The older generation of Shanghainese regard You Dunzi as an afternoon snack.
