Eva and Maite kick off a two-part series on burgers by tracing their roots long before the bun. They begin with the global history of minced meat, follow its path to the United States, where the hamburger starts to take shape, find its perfect match in the bun, and win the heart of America. From early 20th century fears around contaminated beef to the rise of drive-ins and drive-thrus, they explore how car culture transformed the burger into a symbol of freedom, youth, and modern American life, ushering in the age of fast food.
