Sichuan pepper with salt is a seasoning that crops up in many Chinese recipes. You can buy sichuan (or szechuan) pepper in Asian supermarkets, Waitrose and Ocado. To make sichuan pepper and salt seasoning, dry-roast 1 tablespoon of sichuan pepper and 3 tablespoons of sea salt in a heavy-based pan. When the peppercorns start to pop and become aromatic, remove from the heat and allow to cool. Once cool, grind to a powder in a pestle and mortar or spice grinder. Store in an airtight container. Makes 4 tablespoons.
