Liverwurst is manufactured in the same fashion as a cased sausage and dense enough to be consumed like a sausage if desired. The main difference between liverwurst and a traditional cased sausage is its density and texture. A cased sausage uses more meat in its mixture for a firmer texture, whereas liverwurst uses more fat to make it spreadable. You can handle liverwurst much the same as you would a sausage, including how it's prepared and cooked.
