This is a popular Korean dish called Pajeon (“pa” = green onions, “jeon” = pancakes). Instead of salmon, you can also use different seafood, such as shrimp, squid and clams, or make it vegetarian.
Place the salmon fillet in the center of an aluminum foil piece. Season with salt and pepper and pour sake or wine on top (if using).
Wrap the salmon with the foil and cook in the oven or oven toaster for 20 – 25 minutes at 400°F/200°C.
In a small bowl, mix all the 6 ingredients for the sauce and set aside.
In a larger bowl, mix flour, salt, egg, water and sesame oil.
When the salmon is cooked, remove the skin and flake the salmon with a folk.
Add scallions and salmon flakes to the pancake mixture and mix.
Heat a large non-stick frying pan and spray oil.
Pour the pancake mixture and cook both sides for about 5 minutes each until lightly browned. (To flip the pancake, you can place a large plate on top of the frying pan, invert the pan over the plate, and transfer the pancake to the frying pan to cook the other side.).
Transfer the pancake to a large plate and slice it.
