Read this passage from the article:

Making [a Snickers] started with peanut butter nougat, a soft, sticky candy made from sugar and egg whites. The nougat was poured on a huge tray and topped with caramel and peanuts to make the inside of the bar. After that, the nougat-caramel-peanut creation was cut into slices. Finally, each piece was hand-dipped in melted chocolate.
