Peppercorns are the fruits of an evergreen tree, from which the spice pepper is yielded. Pepper is an excellent seasoning for virtually every culinary purpose except sweets. Black, white and green peppercorns are the products of the same plant but each is harvested and processed differently. Liked for its spicy and hot flavor, peppercorn is an indispensible part of the cuisines of India, Indonesia, and Malaysia.
