My all-time favorite chicken recipe is Pon Pon Chicken, and I see references online to Pon Pon Shrimp and Pon Pon Pork. I took the chicken recipe from The Chinese Cookbook by Craig Claiborne and Virginia Lee (1972). They explain the meaning of some recipe names but not this one. I always assumed “pon pon” meant “sesame,” but I see now that is ma zhi. Becuase it calls for Sichuan peppercorns, I presume it’s a Sichuan (Szechwan) recipe.
In case it helps to answer the question, the recipe is made with chicken, sesame paste, sesame oil, hot oil, soy sauce, vinegar, scallions, brewed tea, sugar, Sichuan peppercorns, and garlic.
