Spicy peppers, also known as chili peppers, belong to the genus Capsicum. They are known for their heat, which comes from a compound called capsaicin. This heat is measured on the Scoville scale, which quantifies the spiciness of different pepper varieties. Common types include jalapeños, habaneros, and serranos, each offering a unique flavor and level of heat. These peppers are widely used in cuisines around the world, adding flavor and spice to dishes. In addition to their culinary uses, spicy peppers are also rich in vitamins, particularly vitamin C, and may have health benefits, such as boosting metabolism and reducing inflammation.
