Sausages are, given what they give in return, way to easy to create.
Drying (rack, eg. salami), boiling (cauldron, eg. bear banger), baking/smoking (oven, eg. Boar Baloney) should be, depending on type of sausage, required steps to make them eatable, only stuff like liverwurst should be consumeable directly (and be combined with bread and cucumber to get something better).
