Pajeon

Whisk together water, eggs, glutinous rice flour, and Korean pancake mix in a large bowl. Add leeks, chilies, squid, and shrimp, if using, and mix until well combined.

Heat oil in a pan over medium heat. Pour about 1/3 cup batter into pan; cook for 3 minutes or until golden brown. Flip and cook the other side. Repeat with remaining batter.

Make the dipping sauce: mix all ingredients together in a small bowl. Serve pajeon with dipping sauce on the side.
