Chile peppers are the fruits of plants from the genus Capsicum. They come in various shapes, sizes, and colors, ranging from small and green to large and red. Chile peppers are known for their spicy flavor, which comes from a compound called capsaicin. This compound can vary in concentration, making some peppers mild while others are extremely hot. These peppers are used in many cuisines around the world, adding heat and flavor to dishes. Common varieties include jalapeño, habanero, and bell pepper, the latter being sweet and not spicy. Chile peppers can be eaten fresh, dried, or powdered, and are often used in sauces and salsas.
