What is Gristle?
A few too many encounters with gristle, and even the most avid omnivore might be tempted to turn vegetarian. It’s chewy, rubbery, flavorless, and altogether unpleasant, but what exactly is gristle? Read on…
Your average cut of raw meat is made up of four components: muscle tissue, fat, collagen, and elastin. The muscle tissue is what we actually end up eating. The fat melts as the meat is cooked, giving this muscle tissue flavor and texture.
Collagen is a type of connective tissue, meaning it holds together or connects muscle tissue together. Initially very tough, collagen breaks down under heat, giving meat a tender, silky mouthfeel.
And finally we have elastin. This is another type of connective tissue and is primarily found in an animal’s ligaments and surrounding muscle groups. It’s stretchy and incredibly tough. Unlike collagen, elastin does not break down when the meat is cooked, and this is where we get gristle.
You get a lot of gristle in cuts of meat that come from the shoulders, legs, and haunches of an animal, like top round and chuck. It’s easy to cut away because it’s usually visible in clumps near where the muscle connected to a bone or as a silvery film across the surface of meat. If you don’t manage to cut it away before cooking, it won’t harm the flavor or texture of your cooked dish – it’s just unpleasant for the person who gets that chewy mouthful!
