Black and white peppercorns are native to Asia and are an imported product in Germany. They are the small berries of a plant called Piper Nigrum. Both black and white pepper corns come from the same basic plant, and are used abundantly in all German dishes. Black kernels have been picked still red when the pepper berry is not yet fully mature while white kernels are simply the mature pepper product removed of its outer coating. The difference is in appearance and in flavor. Black peppercorns have a stronger flavor; white peppercorns have a milder aroma.
