I have not heard of this kind of sausage, I must have lived a sheltered life, so I went looking for recipes. Several different ones, some with salt and seasonings and some just meat, potatoes and onions.
3 lbs ground pork
2 lbs ground beef
5 lbs potatoes, finely diced
5 onions, finely diced
4 tbsp salt
3 tsp allspice
2 tsp pepper
½ cup milk
sausage casings (pork casings)
10 lbs ground chuck Have your butcher grind the chuck and pork together
5 lbs ground pork
30 lbs potatoes peeled and quartered
5 lbs sweet onions peeled and quartered – you can also use a white onion
pork sausage casings
There are two I found, just posting to see which general direction you went.
