Mustard (condiment) mixed with horseradish and dried for storage, which were then exported to London and other parts of the country, and are even mentioned in William Shakespeare's play "King Henry the Fourth, Part II". The use of mustard as a hot dog condiment is said to have been first seen in the US at the 1904 St. Louis World's Fair, when the bright-yellow French's mustard was introduced by the R.T. French Company. Mustard is most often used at the table as a condiment on cold meats.It is also used as an ingredient in mayonnaise, vinaigrette, marinades, and barbecue sauce. It is
St. Louis part of the remaining lagoon at the foot of Art Hill, and the Flight Cage at the St. Louis Zoo. The Missouri History Museum was built afterward, with the profit from the fair. But 1904 left other assets to the city, like Theodore Link's 1894 St. Louis Union Station, and an improved Forest Park. The city is divided into 79 government-designated neighborhoods. The neighborhood divisions have no legal standing, although some neighborhood associations administer grants or hold veto power over historic-district development. Several neighborhoods are lumped together in categories such as "North City," "South City," and "The Central West End."
