Boterhamworst is a popular cooked, smoked sausage, of
Dutch origin. Most boterhamworst is consumed in
Holland.
It's constituent meats are veal and pork, both of which are finely chopped. Added to the base meat mix is coarse cubes of pork fat, and seasonings.
The sausage is sold hung, salami-style, and is frequently used as an ingredient in more complex dishes in Holland. It is also sold by the slice in delicatessens.
According to my fellow nodist Hooverdirt, botterhamworst is sold as bologna in Canada and the USA.
