Fresh red chilli refers to the unripe but fully matured fruits of the chilli plant, usually bright red in color, with a vibrant, pungent flavor and varying levels of heat. They are used widely in cooking to add spice, heat, and a bright color to dishes. Fresh red chillies are common in cuisines around the world, such as Indian, Thai, Mexican, and many others. They can be used whole, sliced, or finely chopped, depending on the recipe, and can be eaten raw, cooked, or pickled. The heat of the chilli comes from capsaicin, a compound found mainly in the seeds and inner white membrane of the fruit.
