By the beginning of the twenty-first century, the major table condiments were ketchup, mustard, hot sauce, and mayonnaise. Mustard seeds arrived with European colonists and were converted into powdered form and sold in stores by the eighteenth century. Ketchup became an important condiment in America during the late eighteenth and early nineteenth century, but mayonnaise did not emerge until the last decade of the nineteenth century. The use of all three condiments increased as they became interconnected with the rise of fast foods, particularly hot dogs, hamburgers, and french fries.
