Peel the white radish and cut into thin strips. A mandoline does a good job, however, the taste will not be retained as well as with hand chopping.
Add the chopped green onions, half a teaspoon each of salt and white pepper, the sesame oil, and stir well. Set it aside.
Crack the eggs into a separate bowl and add the water and flour.
Take a whisk and mix evenly and thoroughly. Chopsticks produce a smoother effect, but you can save some time using a whisk.
Add the mixture of the green onion, radish, and 1 teaspoon each of salt and pepper to the batter.
Start heating a 20 cm flat-bottomed nonstick pan on the stove and add 15g of peanut oil after preheating for 1 minute.
With a spoon, scoop out enough batter to cover the bottom of the pan, without making it too thick.
Use a spatula to turn the pancake over and then fry for about a minute.
