I saw a recipe very similar to this the other week and wanted to make it. However, it turns out Sichuan peppercorns are quite difficult to find and after visits to many supermarkets I came up with nothing. I wound up getting the peppercorns off of Amazon. They were well worth the purchase. They give of a tingly and numbing spiciness that I had never tasted before. This dish bring a lot of heat, but the sensation of the peppercorns makes the heat from the chilies tolerable. This dish is best served over rice noodles. If you want to try a new Chinese dish and you like spicy food I recommend giving this dish a shot.
