Black peppercorns are actually green peppercorns that have been cooked and dried out. Black peppercorn has a strong, pungent flavor. Added whole, they bring gentle heat. Use them in herb sachets to bring flavor to soups and stews or, add them to brines for chicken, turkey, and pork roasts. Black peppercorn is used universally on all types of foods, only limited by one's imagination.
