Leg or brown meat on turkey makes better burgers because the meat is juicier. Breast meat is fine, and is extremely good for you, but needs more attention and can cook dry. I have a couple of great tricks to avoid this: add a little mayonnaise to keep the burger beautifully juicy and tasty; and dust with a little cornflour to trap the juice in the burger. Serve these juicy turkey burgers with a salad side of rocket, cucumber, pepper and tomato.
