#2 Peanut Butter

Early peanut-butter-making machines were developed by Joseph Lambert, who had worked at John Harvey Kellogg's Battle Creek Sanitarium, and Dr. Ambrose Straub who obtained a patent for a peanut-butter-making machine in 1903. "In 1922, chemist Joseph Rosefield invented a process for making smooth peanut butter that kept the oil from separating by using partially hydrogenated oil"; Rosefield "...licensed his invention to the company that created Peter Pan peanut butter" in 1928 and in "...1932 he began producing his own peanut butter under the name Skippy". Under the Skippy brand, Rosefield developed a new method of churning creamy peanut butter, giving it a smoother consistency. He also mixed fragments of peanut into peanut butter, creating the first "chunky"-style peanut butter. In 1955, Procter & Gamble launched a peanut butter named Jif, which was sweeter than other brands, due to the use of "sugar and molasses" in its recipe. As the US National Peanut Board confirms, "Contrary to popular belief, George Washington Carver did not invent peanut butter."
