Okay kiddo, so Fergus Henderson is a chef who is really good at cooking meat and other yummy foods. He even wrote a cookbook called "The Whole Beast: Nose to Tail Eating" that teaches people how to use all parts of an animal when cooking, not just the "normal" parts like the meat you usually see in the grocery store.
He also runs a restaurant called St. John in London, where he cooks all sorts of interesting things that might be a little different than what you're used to, like pig's ears or lamb's kidneys. Even though some people might think these things sound weird, a lot of people really like his cooking because it's tasty and done in a special way!
