John, here is a recipe from a book Cook and enjoy.

5kg beef
1kg pork
1.5 kg pork fat
50 ml salt
12.5 ml pepper
37.5 ml coliander(fine)
12.5 ml gloves (fine)
23 ml wonder pepper (fine)
7.5 ml nutmeg (fine)
150 to 200 ml viniger, I use brown vineger

Cut the meat and the fat in blocks and mix.
Mix in the vinegar
Mix the spices and sprinkle over the meat.

I first mince it with a 10 mm plate, then mix it and then mince it with a 3 mm plate. Mix again thoroughly gefore you put it in the skins.

The beef can be replaced with venison and the pork with beef. The pork fat can be replaced with the tail fat of sheep. If you use the tail fat of sheep you cannot keep it to long.

You can also play around with your spices. The best way to test your mixture is to take a bit of raw mixture and smell it and taste it. You can alsways ad a bit. I love a lot of Coliander, but everybody got his own taste.

You can also play around and add some cheese, or garlic. Instead of mincing the pork fat you can cube the fat and mix it in. Your imagination can do the rest.

Enjoy
