A hot dog (less commonly spelled hotdog) is a food consisting of a grilled or steamed sausage served in the slit of a partially sliced bun, and much debate has centered around whether or not it can be considered a sandwich; the term can also refer to the sausage itself. The sausage used is a wiener (Vienna sausage) or a frankfurter (Frankfurter Würstchen, also just called frank). The names of these sausages also commonly refer to their assembled dish. Hot dog preparation and condiments vary worldwide. Typical condiments include mustard, ketchup, mayonnaise, relish, and cheese sauce, and common garnishes include onions, sauerkraut, jalapeños, chili, grated cheese, coleslaw, bacon, and olives. Hot dog variants include the corn dog and pigs in a blanket. The hot dog's cultural traditions include the Nathan's Hot Dog Eating Contest and the Oscar Mayer Wienermobile.
These types of sausages were culturally imported from Germany and became popular in the United States. It became a working-class street food in the U.S., sold at stands and carts. The hot dog became closely associated with baseball and American culture. Although particularly connected with New York City and its cuisine, the hot dog eventually became ubiquitous throughout the US during the 20th century. Its preparation varies regionally in the country, emerging as an important part of other regional cuisines, including Chicago street cuisine.

    How Does Hot Air Rise and Affect Weather Systems?

    I know a hot air balloon goes up because the density of the hot air inside is lower. But what about free air, not trapped in a balloon? You often see exactly the same explanation, hot air is less dense so it goes up, but this does not make any sense if you consider the fact that air is just a...
