Peppercorns can also be found in different varieties, including white, green, and pink, each offering unique flavors and culinary uses. These tiny seeds are one of the most popular spices worldwide, often used to enhance the taste of various dishes. In addition to their culinary applications, peppercorns have a long history in trade and were once considered so valuable that they were referred to as "black gold."
