Notes
Homemade Szechuan pepper salt1. In a pan, without oil, heat 2 tablespoons (35g) of Sichuan peppercorns, 4 tablespoons (70g) of salt, and 1 star anise over low heat. Stir-fry until the salt turns slightly yellow (about 6 minutes). Let it cool and set aside.2. After cooling down, grind the mixture into powder using a blender. Then, sift the powder and transfer it into a bottle for storage.* A simpler method would be to use 1 tablespoon of Sichuan peppercorn powder and 4 tablespoons of salt. However, the drawback is that the fragrance may be less intense compared to the freshly ground mixture.
