Bell peppers (Capsicum annuum) are one of the most widely grown and versatile members of the chilli pepper family. Unlike their fiery relatives, bell peppers contain virtually no capsaicin—the compound responsible for the burning sensation in hot chillies—giving them a Scoville Heat Unit (SHU) rating of 0. Their crisp texture, vibrant colours, and naturally sweet flavour make them a favourite ingredient in cuisines around the world.
