Frank's Redhot is a hot sauce made from a variety of cayenne peppers. Frank's Redhot's recipe dates to 1896 to the Frank tea and spice company in Cincinnati,Ohio. Owner Jacob Frank would in 1918 contract for the Estilette Pepper Farm in Louisiana where Adam Estilette and Frank became business partners. The two men mixed spices, vinegar, garlic, cayenne peppers, allowed them to age, and created the original blend of Frank's RedHot as it first appeared on the market in 1920.
