The Kitchen Item Vincent Price's Grandfather Invented

While actor Vincent Price may be best known for his horror movies, his grandfather created one of the most helpful kitchen items of all time. Vincent Clarence Price came up with the first cream of tartar baking powder as a way to help his mother with her biscuits, according to St. Louis magazine. His mother liked to make biscuits, but didn't eat them because they were too hard to digest (via Vincent Price: A Daughter's Biography). Price experimented extensively, eventually discovering that a chemical byproduct of winemaking could be added to the biscuits to improve their overall quality and improve their digestibility. Scientifically speaking, cream of tartar is known as potassium hydrogen tartrate (via Taste of Home).

This was just a little creation that he whipped up in his spare time from working as a pharmacist and homeopathic doctor. But Price started to sell his invention door-to-door and later patented it. He joined forces with a banker named Charles R. Steele in the 1860s, and together they formed a company to manufacture Dr. Price's Cream Baking Powder. He went on to create other products, including flavored extracts and breakfast foods, and to write a series of successful cookbooks, according to "Cooking Price-Wise: A Culinary Legacy."
