Sorry for coming in late on the subject. Ran across these little guys whilst in China 3 years ago. They are not properly classified as a pepper, but more so as a "peppercorn." They =do= have the effect of numbing the tongue when very fresh, with a strong citrus flavor. Not particurally warm, but it is a strange effect! Still have some in the freezer from Shanghai, and they keep well that way, although the citrus flavor fades quickly. Take care.....from Kurt (CH#1155) in Angleton, Tejas. kfaria@tgn.net ICQ #6471656
