Tibetan Peppercorn is a spice widely grown and consumed in Asia. It is the outer husk of the fruit of the prickly ash tree, Xanthoxylum. It is native to Central, Eastern and South-East Asian. It has an earthy and warm aromatic smell. Other than a fresh and slightly minty taste, when you bite into it, it will taste bitter. However after a while, a numbing feeling will occur on your tongue.
