The sausage isn't stuffed into a casing at all — it's a flat cut of pork belly rolled around herbs and spices, pressed under weight, and thinly sliced once cured.
A flank of pork or veal is seasoned with pepper, allspice, and onion, rolled tight, brined, boiled and pressed until firm, then sliced paper-thin. It's classic deli and market fare across Denmark, often eaten cold on rye bread.
