Prickly-ash tree is a citrus family flowering plant native to mountainous Szechuan region in China. It is a small tree with numerous short spines on both the stems and the leaf petioles, and large knobs on the branches as in lemon. During the winter season the flowers appear in slender cymes which subsequently produce tiny reddish brown berries by the end of spring. The ripe fruits open out to release the round, black seeds from inside. It is this outer coat (husk) which is used as spice whereas seeds are discarded. Sichuan peppercorns are different from black peppercorns which are native to India in plant characters, aroma and hotness. Sichuan peppers feature anise like flavor with slight tangy taste and produce less pronounced pungency than other type peppers.
