Dried ground pepper has been used since antiquity for both its flavour and as a traditional medicine. Black pepper is the world’s most traded spice. It is one of the most common spices added to cuisines around the world. The spiciness of black pepper is due to the chemical piperine, not to be confused with the capsaicin characteristic of chili peppers. Black pepper is ubiquitous in the modern world as a seasoning and is often paired with salt.
