That, my friends, is delicious nutritious stock made from a smoked-turkey carcass and herbs. Why does it look like Jello? Because it was simmered for over 8 hours, which extracted most of the collagen from the bones. Collagen is good for you. And when a collagen-rich stock chills, it gels.
The suspicious-looking layer on top is fat. Which is also good for you, and which retains incredible amounts of flavor. The portion that was scooped out of this container formed the base for a vegetable chowder, easy and satisfying.
