Spicy seasonings are ingredients that add heat and flavor to food. Common examples include cayenne pepper, jalapeño, and black pepper. These seasonings can enhance the taste of dishes, making them more exciting and enjoyable. They are often used in various cuisines around the world, from Mexican to Indian. The heat level of spicy seasonings is measured using the Scoville scale, which quantifies the spiciness based on the concentration of capsaicin, the compound responsible for the heat. Many people enjoy spicy foods for their bold flavors and potential health benefits, such as improved metabolism and increased appetite.
