Rookworst is a Dutch smoked sausage made with either pork, pork and beef, or pork and veal, but in recent years there's also a turkey-based rookworst that's available in most Dutch stores. The meat is typically flavored with saltpeter, nutmeg, and sugar before it is placed into pork intestines and left to smoke over smouldering woodchips.
There are two distinctive varieties of this sausage – Gelderse rookworst and raw rookworst. The Gelderse variety is pre-cooked and sold vacuum-packed, so it can simply be reheated, while the raw variety should be cooked before consumption.
