Used to measure the spiciness of chili peppers, the Scoville scale translates the food's capsaicin concentration into Scoville Heat Units (SHUs). Take your taste buds on a temperature tour from simmering to scorching with this fiery tasting kit. Every collection includes 12 vials of peppers, from the mild heat of New Mexico (500–1,000 SHU) and Ancho Chilis (2000 SHU) to the hottest in the world—the Carolina Reaper (2.2 million SHU). The included booklet is full of information on the Scoville scale and the science of spice, plus recipes and info for each pepper variety. Made in Indiana.
