Sichuan peppercorns are actually berries from an ash tree rather than pepper, but they deliver a ton of heat and a unique citrusy flavor, so we will count them! Dried red chilies are easier to come by in regular grocery stores. However, Sichuan peppercorns can be difficult to track down. Your best bet is to take a trip to a local Asian market where they should be in stock. Otherwise, I find them online.
