Bacon sandwich

A bacon sandwich (also known in parts of the United Kingdom and New Zealand as a bacon butty, bacon bap, bacon cob or bacon sarnie) is a sandwich of cooked bacon. It may be spread with butter, and may be seasoned with brown sauce or tomato ketchup. It is generally served hot. In some establishments the sandwich will be made from bread toasted on only one side, while other establishments serve it on a similar roll as is used for hamburgers.

Bacon sandwiches are an all-day favourite throughout the United Kingdom and Ireland. They are often served in British cafes and delis, and are anecdotally recommended as a hangover cure.

In 2007, researchers at Leeds University evaluated 700 variants of the sandwich, experimenting with different cooking styles, types of bacon, breads, oils, and special additions. Each variant was then ranked by 50 tasters. In conclusion, the best bacon sandwiches are made with "crispy, fried, and not-too-fat bacon between thick slices of white bread."

Another study by the Direct Line for Business listed the top additions to the traditional bacon butty in England. Although the original was still the preferred sandwich, the next top contender was the "breggy" which adds an egg. The next-most-popular accessory was mushrooms, followed by cheese. For sauces, brown sauce was slightly favoured over ketchup. However, food writer Felicity Cloake recommends neither, favouring marmalade and mustard instead.

The BLT is a popular variant of the bacon sandwich with the additional ingredients of lettuce and tomato, but typically served cold.

In Ontario, Canada, peameal bacon sandwiches are a common variation, usually served on a soft kaiser bun, and are considered the unofficial dish of Toronto.

Bacon is a common ingredient in breakfast sandwiches, with the bacon, egg and cheese sandwich as a particularly common variation in New York City.

A Double Down is a sandwich offered by Kentucky Fried Chicken (KFC). The Double Down contains "bacon, two different kinds of melted cheese, the Colonel’s 'secret' sauce... pinched in between two pieces of Original Recipe chicken fillets." It is also available with grilled chicken fillets instead of the Original Recipe fried fillets. The KFC Double Down was initially test marketed in Omaha, Nebraska and Providence, Rhode Island. KFC describes the Double Down as a "sandwich" although it does not have bread.
