Ben & Jerry’s learned how to make ice cream from a $5 course at Penn State. The titular Ben Cohen and Jerry Greenfield were childhood friends. Although Greenfield finished college, he was unable to pursue med school. Cohen, on the other hand, dropped out of school. In 1977, Cohen and Greenfield completed a course on ice cream making from Pennsylvania State University’s Creamery. One of the fun facts no one knows about this famous product: Have you ever wondered why Ben & Jerry’s is so chunky? Ben Cohen has a condition where he can’t smell or taste anything. Instead, he relied on food textures texture to provide variety in his diet. This led to the company’s trademark chunks in their ice cream.
