White pepper consists of the seed of the pepper plant alone, with the darker-coloured skin of the pepper fruit removed. This is usually accomplished by a process known as retting, where fully ripe red pepper berries are soaked in water for about a week, during which the flesh of the pepper softens and decomposes. Ground white pepper is often used in cream sauces, Chinese and Thai cuisine, and dishes like salad, light-coloured sauces and mashed potatoes, where black pepper would visibly stand out.
