1Slice the Fish fillets into thin, bite-sized pieces. In a bowl, marinate the Fish fillets with 15g Shaoxing wine, Light soy sauce, White pepper, and Cornstarch. Mix gently until the Fish fillets are evenly coated, then set aside for 15 minutes.
3Heat 100g Rapeseed oil in a wok over medium-high heat. Add half of the Dried chili peppers and half of the Sichuan peppercorns. Stir-fry for about 30 seconds until fragrant and slightly darkened, being careful not to burn them. Remove the fried chilies and peppercorns from the oil and set aside for garnish.
