Sichuan pepper is the outer pod of the tiny fruit of a number of species in the genus Zanthoxylum, widely grown and consumed in Asia as a spice. Despite the name, it is not related to black pepper or to chili peppers. It is widely used in the cuisine of Sichuan, China, from which it takes its name, as well as Tibetan, Bhutanese, Nepalese, Japanese and Konkani and Batak Toba cuisines, among others. Sichuan pepper has a unique aroma and flavour that is not hot or pungent like black or white pepper, or chili peppers, but has slight lemony overtones and creates a tingly numbness in the mouth (caused by its 3% of hydroxy-alpha-sanshool) that sets the stage for these hot spices.
