Mom usually makes these. They are really good, so I got brave and tried to make them myself. They turned out pretty good for my first attempt. They are so yummy, it's worth the effort.
2 lbs ground beef
finely chopped cabbage
2 whisked eggs
pkg of bean threads (I find them with the Chinese food stuff in the ethnic foods aisle of Fred Meyer)
egg roll skins (these are found in the refrigerated produce section, maybe with the mushrooms in Fred Meyer, I can't quite remember)
cooking oil (lots)
Mix hamburger, cabbage, eggs, seasonings, a little soy sauce. Break up bean threads and pour hot water on them in a bowl so they will soften. After they have softened, add them to the hamburger mixture.
Put about 1/4 cup of the mixture on an egg roll skin and roll up like a burrito.
Use a little water on your fingers to seal the edge. Make sure you don't get it TOO wet, though, or it will fall apart. Place the roll on wax paper on a tray. They will stick together, so put wax paper in between each layer if you stack them. Cook them in oil, (I use my deep-fat fryer with about five inches of oil in it).
The trick is to cook them completely inside without burning the outside. When they turn crispy brown on the outside they should be done. Let them cool and then serve with a mix of soy sauce and ketchup for dipping.
