In a large mixing bowl, combine all the ingredients except the casing. Mix well.
In a large pan, saute the mixture by batch until half cooked. The meat will render oil as it cooks.
Pour out the oil from each batch before cooking the next. Set aside to let cool then stuff the mixture into the casing. Tie 3 inch portions with string.
Poach the sausages in simmering water for 3 minutes then remove at once.
Hang the sausages to dry in the kitchen or in a dry storage area away from flies or rodents.
To serve, fry the sausages in hot oil until crisp and browned or grill over hot coals. Makes 25
