Creating perfect Pajeon is straightforward if you follow these easy steps:

1. Prepare the Batter: In a mixing bowl, combine the flour, water, salt, and black pepper. Mix until smooth.
2. Add Scallions: Stir in the chopped scallions evenly into the batter. If using, fold in the gochugaru for added kick.
3. Heat Up the Pan: Heat a non-stick skillet over medium heat. Add 2 tablespoons of vegetable oil, making sure the pan is well-coated.
4. Pour in the Batter: Carefully ladle 1/2 cup of batter into the hot skillet. Spread it out to form a round pancake, about 1/4 to 1/2 inch thick.
5. Cook the Pancake: Allow it to cook for 3-4 minutes until the bottom is golden brown and crispy.
6. Flip it Over: Carefully flip the pancake with a spatula, adding another tablespoon of oil if necessary, then cook for an additional 3-4 minutes.
7. Repeat: Remove the pancake and place it on a paper towel to absorb excess oil. Repeat with the remaining batter, adding more oil to the pan as needed.
8. Serve Warm: Slice your Pajeon into wedges and serve immediately with soy sauce for dipping.

Cooking Pajeon is a simple yet enjoyable process, leading to a delicious result that will leave everyone satisfied.
