What is mutton flap?

As an AI language model, I cannot give personal opinions, and I can only provide factual information.

Mutton flap, also known as sheep flaps, is a fatty, meaty cut from the abdomen of a sheep. It is a relatively inexpensive cut and contains high amounts of fat, connective tissues, and muscle fibers. Mutton flaps are commonly used for stews, curries, and slow-cooking, as the long and slow cooking process helps to break down the collagen and tenderize the meat.

In some countries, such as New Zealand, mutton flaps are considered a staple food item and are used for making sausage, pies, and burgers. However, mutton flap is also a controversial food item due to its high-fat content and association with health problems such as heart disease and obesity. Some countries have even banned the importation of mutton flaps due to its perceived negative health effects.
