Toast is sliced bread which has been browned by exposure to dry heat. This browning reaction is a form of Maillard reaction. Toasting warms the bread, making it more pleasant to eat for some, and makes it crisp such that it holds toppings more securely. Toasting is also a common method of making stale bread palatable. Toast is often served with butter, cheese, marmalade, or any number of other toppings.
Toasting methods
Using a household toaster
A classic two-slot toasterThe usual method of browning bread is by the use of a toaster, first used in the late eighteenth or early nineteenth century,[1] a small appliance made for that purpose. For a modern toaster, sliced bread is placed into the narrow slots on the top of the device and the desired toast setting is selected (some toasters have more elaborate settings than others). Then, the lever on the side of the toaster is pushed down, simultaneously turning on the heating elements.
Using a grill
Toast can also be prepared under a grill (UK definition, not a BBQ). This method requires turning the toast halfway through the cooking process, making it less convenient than using a toaster. This method also allows a range of toast based dishes to be created, for example cheese on toast where the bread is toasted on one side, turned and topped with cheese before finally grilling the second side.
Using an open fire
Traditionally toast can be prepared on a wood or coal burning open fire, using a toasting fork. As with the grill based method this requires turning the toast during the cooking process.
Preparation and use
Care must be taken while toasting bread to avoid burning toast unless it is desired in that state. Burnt toast is possibly carcinogenic, due to elevated levels of benzopyrene. [2]
Toast is commonly eaten with butter or margarine spread over it. Jams, jellies and other spreads are also commonly used as toppings. In some countries a more popular practice is to spread a yeast extract, such as Marmite or Vegemite on toast. "Beans on toast" and "Eggs on toast" are both very popular simple meals in the United Kingdom. Other methods of preparing toast include to sprinkle a mixture of sugar and cinnamon on buttered toast, creating cinnamon toast.[3] Toast spread with jam, jelly, apple butter or marmalade is commonly associated with breakfast. It is sometimes used instead of fresh bread for making sandwiches (such as a BLT sandwich).
Toast is a common component of many breakfasts, and is also used in some traditional bland specialty diets for people with gastrointestinal problems such as diarrhea, or morning sickness during pregnancy, such as the BRAT diet consisting of bananas, rice, applesauce, and toast.
