レバーソーセージ / Leberwurst (liverwurst / liver sausage)
Liverwurst is a standard German-speaking-region cooked paste-like sausage made with a stated proportion of pork, beef, chicken, or other liver (approximately 10–40% depending on the source). Canned and jarred preserved products (Halbkonserve/Vollkonserve) are also widely distributed.

Reading the bitterness
The German Wikipedia article states that beef liver (Rindsleber), although chemically similar to the comparison liver, produces a bitter taste and dark color. It should be kept in mind that this statement has no footnote and presents general cooking knowledge without a cited source. The production section also describes roughly removing bile, bile ducts (Galle, Gallengänge), and attached visceral fat from the source liver.
Canned and jarred liverwurst (Halbkonserve/Vollkonserve) is known to have bitterness arising through a route separate from bile. A research project at the University of Hohenheim’s Food Materials Science unit (1990–1997) addresses the quality defect called 「苦く焦げたような加熱風味（Hocherhitzungsgeschmack）」 (in translation: "bitter, burnt-like heating flavor") in canned liverwurst and explains that Maillard reactions between free amino acids or ε-amino groups of protein-bound lysine and carbohydrates such as glucose produce the causative substances during high-temperature sterilization.
