Aunt Jemima pancake flour was the first ready-mix food to be sold commercially. It was introduced in 1889 by the Pearl Milling Company of St. Joseph, Missouri. The company was founded by Chris L. Rutt, who named the product after a popular vaudeville character of the time. The pancake flour was a huge success, and the Pearl Milling Company soon began to produce other ready-mix foods, such as cornmeal and baking powder.
