Burnt Deer Meat

Cooking in the furnace feels like free food. The fire is burning for the ore anyway, so you toss the raw deer meat into a spare slot and head out. The catch is timing: a load of ore takes far longer than a steak, and the furnace has no idea the meat is done.

Its own text says eating it damages your health. No recipe takes it and recycling gives nothing back. Give the meat a fire of its own, and the cooked deer meat comes out the way it should.
