This prawn, green peppercorn and grachai stir-fry recipe is a proper Thai stir-fry: hot, fragrant and really fresh tasting. The grachai (a wild ginger) really makes the dish. It gives a great earthy pepperyness, very different from regular fresh ginger. You can find grachai in the fresh section of Thai grocery stores, in Chinatown in London or online at theasiancookshop.co.uk. It lasts for a few weeks unpeeled, so if you see some, purchase it and store it in the fridge.
