花椒

Sichuan Pepper

Sichuan pepper (Chinese: 花椒; pinyin: huājiāo), also Szechuan pepper, Chinese prickly ash, Chinese pepper, rattan pepper, and mala pepper is a spice commonly used in the Sichuan cuisine of China's southwestern Sichuan Province. It's used in many famous Chinese dishes like Mapo Tofu , Chongqing hotpot and many more.
When eaten it produces a tingling, numbing effect that enhances the spiciness of chilis.

Despite its name, Sichuan pepper is not closely related to either black pepper or chili pepper. It belongs to the global genus Zanthoxylum in the family Rutaceae, which includes citrus and rue.
