Sichuan peppercorn is a spice made from the dried husks (pericarps) of the prickly ash tree, prized for its unique tingling-numbing sensation called má là and bright citrus aroma in southwestern Chinese cooking.
History & Origins
Native to Sichuan and adjacent regions of southwestern China, Sichuan peppercorn has been recorded in Chinese texts for more than two millennia, appearing in classical poetry and in imperial materia medica such as the Tang-era Xinxiu Bencao. It traveled along the Tea Horse Road into Tibet and via maritime routes to Japan (where it became known as sansho) and Korea (sancho). The United States banned its importation from 1968 to 2005 over citrus canker concerns, but re-legalized treated Sichuan peppercorns in 2005.
