whisk the eggs, water, soy sauce, sesame oil, kimchi brine, and sugar together in a large bowl
add the flour, and whisk again, it will be thick like pancake batter
put the kimchi in a colander over a medium bowl and let some of the brine drip out, this way your batter will be thick like pancake batter, and not too thin, but don't drain too much liquid
then roughly chop the kimchi and add it to the bowl
add the chopped onion
stir together with a spatula or spoon
put a griddle on to heat at medium, I used a stovetop you can use an electric griddle or a large frying pan
add a little oil to the griddle and let it heat up
drop the batter by small scoops on the hot griddle, make the pancakes roughly 2 inches across, cook for 2-3 minutes per side or until cooked through, you can make the pancakes as big or small as you like, just adjust the cooking time
while the pancakes cook stir together the sauce ingredients
serve the pancakes hot as they come off the griddle
serve the sauce in a pitcher and set out little bowls for people to dip in
keep cooking until the batter is gone and everyone is happy
