This is my own variation of a authentic German-style bratwurst. It's based off a recipe I found years ago on the old Wedliny Domowe site:
German-Style Bratwurst
1 lb Ground Pork, fine ground. For a truly authentic German Brat use a 70/30 mix of pork/veal.
1 tsp Pickling Salt
1/2 tsp Pepper, fine ground (White pepper is traditional, but black works fine)
1/2 tsp Marjoram, ground
1/4 tsp Caraway seeds
1/4 tsp Nutmeg
1/4 tsp Ginger, dried ground
1 egg white (optional - traditionally used to help bind and give a more whitish color, but not absolutely necessary)
1 fl oz Cold Water
Mix the seasonings with the water (and egg white if using), then thoroughly mix into the ground meat. Use as bulk or stuff into hog casings.
