My Uncle owned a Italian sausage and roast beef resturant on the southeast side of Chicago, this is his receipe the best I can figure.
10 lbs pork butt
6 tbls kosher salt
4 tbls course ground black pepper
2 cups ice water
stuff in hog casings and cook over a charcoal fire
and smother in peppers and onions.
I also add 4 tbls of crushed red peppers to the meat mix to spice it up
This is a very simple sausage with a robust flavor.
Living in Florida I have developed a taste for Cuban food, so I Cubanized the peppers and onions
I fry peppers, onions, garlic (one garlic for every 2 peppers)and olive oil and add a couple oz's of Mojo and cook utill the onions are turning translucent and finish cooking them on the grill.
