Peppercorns are the fruit of Piper nigrum, an evergreen climbing vine. Black, white, and green peppercorns all come form the same plant, but they are harvested at different times and handled in different ways. To make black pepper, the clusters are plucked when they are not quite ripe. They are then left in piles to ferment. After a few days, the berries are spread out on a mat and left to dry in the sun for two or three more days until they are shriveled and nearly black. To make white pepper, the berry is picked fully ripe. Its outer shrunken skin is rubbed off, exposing the dried, grayish-white pepper inside. White pepper has a milder, more delicate flavor than black pepper, and is useful for adding a peppery flavour to light-colored sauces and soup without adding black color. White pepper is popular in European cuisines.30g Glass JarFrom: USA
