I Am Curious Zanthoxylum

The FDA had banned its import to the US from 1968 til 2005.  And unless you've eaten this peppercorn, you've never tasted anything quite like it (no culinary elitism, it's the truth!).  How does one describe something completely different from ordinary experience?  To me it tastes like spicy cilantro that blooms in the mouth.  Fellow diners have likened it to some variety of Evergreen, and the friendly Wikipedia hints at its "lemony overtones".  To eat it is to forge a new neural pathway, to teach the brain in its old age that sometimes new experiences are beyond its capacity to avoid.  Plus, it makes your mouth go numb.
