The 1861 English recipe book Mrs. Beeton's Book of Household Management includes a recipe for placing sandwiches of brown bread and butter with 1⁄2-inch (13 mm) slices of "a nice fat Cheshire or any good rich cheese" into an oven, and serving when the bread becomes toasted.[1]
A grilled cheese sandwich is made by placing a cheese filling, often cheddar or American cheese, between two slices of bread, which is then heated until the bread browns and the cheese melts. A layer of butter or mayonnaise is usually added to the outside of the bread for additional flavor and texture. Alternatives may include additional ingredients such as meat, peppers, tomatoes, or onions.[4]
A grilled cheese may also be made in a sandwich toaster, particularly in the United Kingdom where the dish is normally called a toasted cheese sandwich or cheese toastie.[5]
Microwavable frozen toasted sandwiches are available in supermarkets in a variety of locations. One example is the McCain Micro Toastie, which was launched in supermarkets in the UK in 2002.[8]
