The first product resembling baking powder was created by English chemist Alfred Bird in the late 1840s. Bird combined cream of tartar (an acidic powder composed of potassium bitartrate) and baking soda, keeping the two apart until they were to be used so they wouldn’t react too early. Unfortunately, cream of tartar was an expensive byproduct of winemaking that had to be imported from Europe, meaning that it was out of reach for many poorer Americans. In 1856, this need for a viable alternative drove a young chemist Eben Norton Horsford to create and patent the first modern baking powder. Horsford worked at a time when chemistry was only just beginning to be considered a respected field, and ended up creating the first modern chemistry lab in the United States at Harvard University. By boiling down animal bones to extract monocalcium phosphate, Horsford developed an acid compound that could react with baking soda to create those desirable CO2 bubbles. “It’s really the first chemical that opens the floodgates for chemicals in food,” Civitello says.
