White pepper is a spice made from the dried seeds of the pepper plant, specifically the fully ripe berries with the outer skin removed. It has a milder, more delicate flavor than black pepper, with a subtle heat and slightly earthy notes. White pepper is commonly used in light-colored dishes, such as white sauces, soups, and mashed potatoes, where black pepper's dark flecks might be undesirable. It is also a popular ingredient in Asian and European cuisines, providing a refined peppery taste without overpowering the dish.
