Pink peppercorns are actually not related to other peppercorn varieties at all, and come from South America rather than Asia. They're milder and fruitier than black peppercorns, and can replace them or be used in a blend with other peppercorns. Although generally fine to consume, those prone to tree nut allergies might want to avoid these as they are related to cashews.
