Did you know?

Margarine was formulated in 1869 by Hippolyte Mège Mouriès of France in response to Napoleon III's offering of a prize to whoever could succeed at producing a viable low-cost substitute for butter. Mège Mouriès' concoction, which he dubbed oleomargarine, was achieved by adding salty water, milk, and margaric acid to softened beef fat. By the turn of the century, the beef fat in the original recipe had been replaced by vegetable oils. 

In 1886, New York and New Jersey prohibited the manufacture and sale of yellow-colored margarine, and by 1902, 32 U.S. states had enacted such prohibitions against the coloration of the spread. (Folks got around this by mixing yellow food coloring into the white margarine.) In 1950 President Truman repealed the requirement that margarine be offered for sale only in uncolored state, which led to the widespread production of the yellow margarine that has come to be the norm.
