Start by mixing the salt into the meat in a large bowl.
Grate the onion finely on a grater and mix all the ingredients together with the meat.
Mix well and let the meat mixture rest in the refrigerator for at least 15 minutes, ideally longer.
Make sure the meat mixture is at room temperature before frying. This ensures they are fried rather than boiled.
The krebinetter should each weigh 90 grams and be shaped oval. They should be double breaded: that is, coat them in flour, then beaten eggs, and then bread crumbs, and repeat the process once more. Melt the butter over medium-high heat in a large pan and let it foam up before adding the krebinetter to the pan.
Fry them for about 6 minutes on each side and they are now ready for serving.
Optionally, use the cooking fat to pour over your krebinetter or for the sauce.
