The most popular flavor of Jell-O is strawberry. Traditionally, all of the red flavors have dominated as the top-selling choices. Besides strawberry, these include raspberry and cherry.
In addition to the red flavors, lime Jell-O is also very popular. In 2001, Jell-O became the official favorite snack food of the state of Utah, though there is no mention of a specific flavor. During the 2002 Winter Olympics located in Salt Lake City, Utah, bowls of lime Jell-O were depicted on official souvenir pins. The popularity of lime Jell-O can also be attributed in part to its use in Jell-O based fruit salad molds and other recipes.
