It is made from pork: pig’s liver and lean meat, plus for fat, either pancetta (pork belly) or minced lard.
The liver, meat and fat are minced and mixed with saltpetre.
Spices including cloves, sometimes cinnamon sticks are put in wine, and the wine is mulled. The mulled wine is then mixed into the meat mixture, which is then packed in a wide natural casing (intestine or bladder.)
The sausage is aged in a warm room 64 to 68 F (18 to 20 C) for 7 days.
It will weigh 21 to 25 oz (600 to 700g), and be soft and dark red.
The liver taste comes through.
The sausage needs cooking.
