Chex Mix is a type of snack mix that includes Chex breakfast cereal (sold by General Mills) as a major component. The original version of Chex Mix is based on a homemade version of the snack which was made for many years but there are also several commercially produced varieties of Chex Mix. Though contents vary, the mixes generally include an assortment of Chex cereals, chips, hard breadsticks, pretzels, nuts or crackers. Recipes for homemade Chex mix are printed on Chex cereal boxes and are available online. Chex cereal was introduced in 1888 by Ralston Purina. By 1952, recipes for 'Chex party mix' appeared on boxes of Chex cereal. However, it was not until 1985 that pre-packaged products were introduced commercially by Ralston Purina and the trademarks registered. Chex party mix became popular as a holiday treat when purportedly in 1955, the wife of a Ralston executive in St. Louis served the snack at a holiday function.
