Sichuan and Sansho — Pepper Berries That Create A Numbing and Tingling Sensation

The Sichuan Pepper is actually the lemon-flavored, numbing berry of the Prickly Ash Tree (Zanthoxylum simulans).

Sichuan Peppers cause a numbing and tingling or “buzzing” on the tongue. This effect is created by a substance in the berries called hydroxy-α-sanshool.

The term “sanshool” comes from the Japanese term for the Japanese peppersanshō (山椒) (literally, mountain pepper).

Dried Sichuan Peppercorns also known as Zanthoxylum simulans seeds

Flavor-wise, the berries have notes of pepper, lemon, and wood.
