Clean white radish and cut into really thin shreds.I recommend using a tool for beginner.
Sprinkle salt on those shreds and mix well. Put aside for 10 minutes.Then squeeze the water out. Have a taste here. If the shreds are too salty, wash it with purified water and then squeeze the water out.
In a large mixing bowl, add sugar, sesame oil and vinegar in with white radish shreds and mix thoroughly.
Spread the chili pepper powder on the surface of the white radish shreds. Heat up 1 tablespoon vegetable oil in pan and then pour the hot oil on the chili powder. Mix everything well.
Garnish some roasted sesame seeds and green onion before serving.
