Mix all the ingredients (except the oil) in a bowl, stir the batter to blend well. Combine all the ingredients of the Dipping Sauce in a saucer.
Heat up a pan and coat with some oil. Ladle some batter onto the pan to form a mini round pancake. Pan-fry for a couple of minutes until the bottom surface turns slightly brown, flip it over and cook the other side until slight brown. Dish out and repeat the same for the remaining batter.
Serve the pajeon warm with the Dipping Sauce.
If you don't use the kimchi juice, add the same quantity (2-3 tablespoons) of water to the batter.
