is distilled vinegar the same as white vinegar for cooking
Vinegar The term "distilled vinegar" as used in the United States (called "spirit vinegar" in the UK, "white vinegar" in Canada[8]) is something of a misnomer because it is not produced by distillation but by fermentation of distilled alcohol. The fermentate is diluted to produce a colorless solution of 5% to 8% acetic acid in water, with a pH of about 2.6. This is variously known as distilled spirit, "virgin" vinegar,[9] or white vinegar, and is used in cooking, baking, meat preservation, and pickling, as well as for medicinal, laboratory, and cleaning purposes.[10] The most common starting material in some regions, because of its low cost, is malt,[11] or in the United States, corn. It is sometimes derived from petroleum.[12] Distilled vinegar in the UK is produced by the distillation of malt to give a clear vinegar which maintains some of the malt flavour.[11] Distilled vinegar is used predominantly for cooking, although in Scotland it is used as an alternative to brown or light malt vinegar. White distilled vinegar can also be used for cleaning, and some is actually sold specifically for this purpose.
Fast food restaurant Some historians concur that A&W, which opened in 1919 and began franchising in 1921, was the first fast food restaurant (E. Tavares). Thus, the American company White Castle is generally credited with opening the second fast-food outlet in Wichita, Kansas in 1921, selling hamburgers for five cents apiece from its inception and spawning numerous competitors and emulators. What is certain, however, is that White Castle made the first significant effort to standardize the food production in, look of, and operation of fast-food hamburger restaurants. William Ingram's and Walter Anderson's White Castle System created the first fast food supply chain to provide meat, buns, paper goods, and other supplies to their restaurants, pioneered the concept of the multi-state hamburger restaurant chain, standardized the look and construction of the restaurants themselves, and even developed a construction division that manufactured and built the chain's prefabricated restaurant buildings. The McDonald's Speedee Service System and, much later, Ray Kroc's McDonald's outlets and Hamburger University all built on principles, systems and practices that White Castle had already established between 1923 and 1932.
