In
butchery, butterflying transforms a thick, compact piece of meat into a thinner, larger one. The meat is laid out on a cutting board and cut in half parallel to the board almost all the way to the other side, leaving a small "hinge", which is used to fold the meat out like a book. This technique is often used as an alternative to, or in conjunction with, pounding out the meat with a
meat mallet to make it thinner. For
leg of lamb, it is generally followed by boning. Common uses of this technique include creating thin cutlets from chicken breasts for dishes such as
chicken piccata, or rendering lamb leg roasts suitable for making roulades. It can also be a first step to dicing chicken or slicing it into strips. Because the butterflying technique results in a thinner piece of meat or poultry, it allows for quicker cooking times and often more even cooking. ==Poultry and "spatchcocking"==
