Pink Reunion Island Peppercorns are whole pink pepper berries that differ from true peppercorns in both botany and heat. They are not part of the Piper nigrum family and lack the sharp pungency associated with black, white, or green pepper. Sometimes called pink or rose peppercorns, they are commonly blended with black, white, and green peppercorns to create a flavorful and colorful alternative for use in pepper mills. They are not recommended for use alone in a pepper grinder, as their softer inner seeds can clog the grinding mechanism. Pink peppercorns are members of the cashew family, so they should be treated as a potential allergen.
