Boil the beef in water till it falls apart or chop it, it took me about a good 4 hour on simmer. Save the beef broth you are going to need it for the roux. You don't have to use beef you can use pork or ham, whichever you prefer. Make a roux and this is how you do it. Melt the margarine in the skillet, add the minced onion, cook till translucent, then add the flour. Keep stirring. Then add the beef broth, 1 cup at the time. still keep stirring till you have a nice sauce. Add the seasonings, the shredded or chopped beef and the parsley. Pour onto a cookie sheet and let it cool in your refrigerator for about 2 hours. Then make small balls (golf ball size) or small rolls, those are called kroketten. Wet your hand with the canola oil roll the balls and roll in the four then in the egg mixture and then in the bread crumbs. While I clean up my kitchen from making these bitterballen I put them in the freezer to flash freeze. When your kitchen is all cleaned up again go and deep fry these bitterballen. Eat as an appetizer or eat them on a slice of bread.
