Green peppercorns come from the same plant as black and white peppercorns, but are the pepper berries that have been picked before maturity. Unlike black pepper, which is used mostly as a flavor enhancer, green peppercorns lend a more sophisticated, earthy, hot flavor to dishes. They work well in dishes where they will play the lead role. Green peppercorns are great used in Mediterranean and seafood dishes, brines, and pairings with dijon mustard.
