Similar to Western butterflying, this technique is used to split a flat piece of food into two thinner pieces, which are then used to wrap around a stuffing. Freeze the meat partially to stiffen it (10 to 15 minutes) before you begin.
Hold the cleaver parallel to the cutting board. With a gentle sawing motion, cut into the edge of the piece of food. Continue cutting, keeping the blade parallel to the board.
Stop cutting before the food separates into two pieces; leave about ¼ inch. The meat should unfold like a book.
