Black pepper is a well-known spice that has a strong pungent aroma. This adds the perfect flavor and texture to your food. Whole peppercorns can be purchased and ground using a pepper mill to get the best flavor. The Piper nigrum vine produces peppers in all colors, including black, green, or white. The strongest flavor comes from the black variety. Unripe green peppers can be dried or salted and are used in Asian cuisine. White peppers are black peppercorns that have had their outer skin removed. They are mostly used for artistic purposes such as white sauces.
