Sichuan is one of my favorite cuisines and Fuchsia Dunlop's Land of Plenty: A Treasury of Authentic Sichuan Cooking is my favorite cookbook for authentic dishes. It's such a comprehensive resource for ingredients and techniques with helpful photos, and every recipe I've made goes into my regular rotation. There's a section in the book with four different sauces for cold sliced or shredded chicken. These no-cook sauces are easy to put together with a well-stocked Asian pantry and I make these dishes frequently for lunch. While the book calls for poaching a whole chicken to tenderness with ginger and green onion, I find the sauces are a perfect solution for leftover chicken. The green onions can be left sliced, or made into a paste as they are in this recipe. I use green onions from my garden. Both I'itoi's onions or Egyptian Walking Onions multiply prolifically here in Arizona, and this time I used I'itoi's onions.
TIPS:
Don't confuse "light" soy sauce with low-calorie or low-salt. It refers to a color; light versus dark soy sauce. The easy-to-find Kikkoman is a light soy sauce, although I prefer Pearl River Bridge brand (found at most Asian markets).
I haven't made it with the raw peppercorns as I always have some toasted, ground and sifted in a jar in the pantry. I toast them in a pan, grind in a spice grinder, and sift into a container. It has a very distinct taste so if you're trying them for the first time, go light on this ingredient. When shopping for Sichuan peppercorns, look for fragrance and more husks than seeds. I buy mine from Penzey's. I find they're always high quality with the prized tingling or numbing quality these peppercorns should have.
