Sichuan pepper
Both Chinese and Batak Toba cooking include the idea of 麻 ("má" or "mati rasa"), a tingling numbness caused by spices such as Sichuan pepper. The cuisines of Sichuan province in China and of the Indonesian province of North Sumatra often combine this with chili pepper to produce a 麻辣 "málà", "numbing-and-hot", or "mati rasa" flavor.
