White pepper just like black pepper is also produced from the dried fruit of Piper Nigrum.
The difference between white and black pepper depends upon the time in which the pepper berries are plucked.
Unripe pepper berries are dried to produce black pepper whereas fully ripe berries are used to make white pepper. White pepper is used as whole and in powdered form. They are milder than black pepper with a lesser complex flavour.
They are mainly used in the cuisines that require a peppery taste, but can't afford to see black flecks floating on the dish.
Thus, white peppers are used in white sauces and potato dishes. Certain soups, meat marinades, poultry and spicier dishes in Chinese Cuisine make use of white pepper extensively.
The people who have lost their appetite must buy white pepper online, because it enhances appetite and treats constipation problems.
