Gristle and tendon are connective tissues that form a soft, supportive “skeleton” within the body of an animal, providing structural integrity to the organs and other tissues. These tissues consist primarily of collagen, which is the main component of the body’s connective tissues. When cooked for an extended period of time, collagen transforms into gelatin, a process that can make gristle and tendon much more palatable and tender. However, in their raw state, these tissues are typically considered inedible due to their tough, chewy texture. Despite this, gristle and tendon play an important role in the overall structure and function of an animal’s body, and are therefore highly valued in the culinary arts for their unique properties and flavor-enhancing abilities.
