Inspired by the show Singles Inferno, this recipe details how to make a classic Korean scallion pancake (Pajeon). While the recipe focuses on the original scallion version, you can customize it with additional vegetables like carrots, zucchini, onions, bell peppers, or seafood such as shrimp, squid, mussels, or clams, especially for a Haemul Pajeon. This recipe primarily uses Korean pancake mix, but an alternative batter can be made using 1/2 cup all-purpose flour and 1 tablespoon potato starch instead of the pancake mix.
