Chili peppers come in a range of colors, shapes, and heat levels, with the heat of a pepper determined by its capsaicin content. Capsaicin is the chemical compound responsible for the spicy or hot sensation that chili peppers produce when eaten. Some of the most commonly known types of chili peppers include jalapenos, serranos, habaneros, and Thai bird’s eye chili peppers.
Chili peppers, also known as chillies or hot peppers, are fruiting plants from the genus Capsicum in the nightshade family, Solanaceae. They are widely used in cuisine as a spice to add heat and flavor to dishes, and are also used medicinally for their various health benefits.
