Frozen dough technology was innovated in the bread production process in Europe and the United States in the 1950s and is widely used. The frozen dough process in developed countries is now very mature and standardized, and the use of frozen dough technology in the bread industry is also quite common.
A baguette is a long, thin loaf of French bread that is commonly made from basic lean dough (the dough, though not the shape, is defined by French law). It is distinguishable by its length and crisp crust.
Toast is a form of bread that has been browned by exposure to radiant heat. This browning is the result of a Maillard reaction altering the flavor of the bread and making it firmer so that it is easier to spread toppings on it. Toasting is a common method of making stale bread more palatable. Bread is often toasted using a toaster, but toaster ovens are also used. Though many types of bread can be toasted the most commonly used is "sliced bread", referring to bread that is already sliced and bagged upon purchase and may be white, brown, multigrain, etc.
