Red chillies are the dried, ripened fruits of various chili pepper plants, most commonly of the Capsicum species. They come in a range of colors, but are typically bright red when fully matured and dried. These peppers are known for their fiery heat, which comes from the compound capsaicin, and are often used to add spice and heat to dishes. Red chillies can vary in heat levels, from mild to extremely hot, depending on the variety.
In addition to their heat, red chillies are rich in vitamins, particularly vitamin C and vitamin A, as well as antioxidants like carotenoids, which can help support immune health. They are also used to stimulate metabolism and promote digestion. Red chillies are a key ingredient in many spice blends, such as chili powder, and are used in cuisines around the world, including Indian, Mexican, and Thai dishes.
