Add Szechuan peppercorns in the remaining oil in the wok over LOW heat. Stir fry for 1-2 minutes or until fragrant. Skim and remove the cooked peppercorns if you feel them annoying when enjoying the food later. (Be sure of using low heat and be patient. Over-fried peppercorns bring a bitter taste.) Now add garlic, ginger and dried chili until fragrant. Then add HALF of the leek sections in for a minute.

- Cooking the sliced leek allows you enjoying the deep fragrance as well as the crunchiness and sweetness of the leek produced by different stages of the cooking.
