Charles Elmer Doolin bought the patented recipe for fried corn chips from a man at a gas station in the 1932. With his brand-new recipe and the help of his mother and brother, Doolin created Fritos. But although the chips were fried, Doolin didn't envision Fritos as junk food; rather, he thought they would be nice as a side dish with a salad or a cup of soup.
Doolin was a vegetarian and rarely ate Fritos. On the rare occasion that he did, he preferred the chips to be unsalted. His children occasionally served as taste-testers for his new products, but they, too, didn't eat Fritos regularly. However, they did help Doolin settle on the perfect recipe for Cheetos, another one of his creations that is now considered a popular junk food.
As of 2015, Fritos are available in a variety of flavors, including chili cheese, honey barbecue and lightly salted, which is probably what Doolin himself would have preferred.
