Some like it hot.
The Scoville Scale and Scoville Heat Unit (SHU) were named for scientist Wilbur Scoville in 1912. At the time, Scoville worked for a pharmaceutical company named Parke-Davis where he developed a test called the “Scoville Organoleptic Test” which is used to measure a chili pepper’s pungency and heat.
Originally, Scoville ground up peppers and mixed them with sugar water, then tested them with a panel of tasters who sipped from these sugar-water-pepper solutions. He would then dilute the solutions bit by bit until they no longer burned the tongues of the tasters, after which he would assign a number to the chili pepper based on the number of dilutions needed to kill the heat. The measurements are divided into multiples of 100. Note that 1 part per 1,000,000 dilutions of water is rated at 1.5 Scoville Units. Pure capsaicin, the stuff that makes chili peppers hot, is rated between 15 – 16,000,000 Scoville heat units.
This is incredibly HOT. So where is the fun?
