History: Despite the name, Sichuan pepper isn’t actually a “pepper” at all, but the dried husk of the prickly ash fruit. It is native to the mountains of southwest China, where the shrubs have grown wild for thousands of years. By the Han dynasty (206 BC-220 AD), Sichuan pepper had become firmly rooted in Chinese cuisine, especially in the Sichuan province for which the spice is named.

Sichuan pepper didn’t reach global kitchens until the 20th century.

Interesting Facts: The famous numbing properties originate from hydroxy-alpha-sanshool, which interacts directly with nerves that regulate touch and temperature, causing a tingling sensation.

Uses: Sichuan pepper is a key ingredient in the cuisine of Sichuan Province, China. It is often combined with chilies to create the hot and cool sensation for which the cuisine is known. It is also one of the spices in the spice blend known as Chinese 5-spice.

Selection & Storage: Look for husks that are bright and clean with a reddish hue. Whole spices are always recommended over pre-ground ones, as they tend to lose their flavor quickly.

Store in an airtight container away from excess heat, light, and humidity.
