I thought I should add something since Young K recommended to the cooking group to check it out.
I made Gangwondo style gamjajeon this afternoon as a snack for my parents and students. I've looked at this recipe for a couple of years and thought about making it but never did until two weeks ago when I felt a burst of ambition and whipped up a batch.
The recipe I use is adapted from Hi Soo Shin Hepinstall's "Growing up in a Korean Kitchen". Egg and cornstarch are mixed together and then chopped peppers, mushrooms, green onions and garlic are added.
The only complaint was that I should have doubled the recipe.
