Whole chili refers to the dried, ripe fruit of the Capsicum plant, specifically when it is used in its entirety, rather than ground into powder. These whole chilies are valued for their ability to impart both a vibrant color and a pungent, spicy flavor to dishes, due to compounds called capsaicinoids. They are a versatile ingredient used in cuisines worldwide for various purposes, including curries, chutneys, sauces, and pickles.
