White pepper is a spice produced from the dried fruit of the pepper plant, Piper nigrum, as is black pepper. It is usually milder than black pepper, with less complex flavor. Both whole and ground white pepper are available.White pepper, like black pepper, is made from the berries of the pepper plant, also known as the Piper nigrum. Unlike black pepper, however, white pepper comes from berries that are picked at full ripeness. These berries are then soaked in water to ferment. Finally, the outer layer is removed leaving only the inner seed.Because the skin is removed, some of the flavor is taken, including the piperine. As a result, white pepper tends to be more mild than black pepper.
