Bacon press used for bacon flattening for a number of years, the press is typically made of a flat section of heavy cast iron, with a handle attached. The earliest models were made completely of cast iron, but since the early 20th century, the handles have been constructed of wood in most cases.
The press is used to flatten bacon as the strips are cooked in a pan or on an open grill. Because of the cast iron construction, it helps to hold in the heat while it prevents the incidence of curling bacon. The result is that the meat will cook a little faster when a press is used, and will most certainly yield flat and relatively uniform slices of bacon for the breakfast table.
Along with the bacon press models that are constructed for use in the home kitchen, commercial versions have been on the market for years. These commercial models are simply larger versions of the home press, and serve quite a few functions in local grilles, restaurants, breakfast bars.
