Preparation: Rinse the liver under cold water to remove any blood or impurities. Trim any connective tissue or tough parts from the liver.
Grinding the Meat: Cut the liver and pork belly or shoulder into chunks that will fit into a meat grinder. Grind all the meat using a medium-fine disk into a large mixing bowl. If you don’t have a grinder, you can also use a food processor, but ensure not to over-process; it should retain a bit of texture.
Seasoning: Add salt, pepper, allspice, marjoram, and chopped onion to the ground meat and mix thoroughly. It’s essential to ensure that the seasonings are distributed evenly.
Cooling and Storing: Once cooked, remove the liverwurst from the water and allow it to cool to room temperature. If you used a mould, let it cool inside the mould. Once cooled, transfer to the refrigerator and let it set and chill for at least 4 hours or overnight.
This liverwurst should be stored in the refrigerator and consumed within a week. If you’re planning to store it longer, consider freezing it. Before serving from the freezer, allow it to thaw in the refrigerator.
