A hot pepper is a type of chili pepper known for its spicy flavor, which comes from a compound called capsaicin. These peppers are commonly used in various cuisines around the world to add heat and enhance the taste of dishes. They can vary in heat levels, measured on the Scoville scale, which quantifies the spiciness based on the concentration of capsaicin. Hot peppers come in many varieties, including jalapeños, habaneros, and ghost peppers. They can be consumed fresh, dried, or in sauces, and are often used in salsas, marinades, and soups. In addition to their culinary uses, hot peppers are also believed to have health benefits, such as boosting metabolism and providing antioxidants.
