@faun the global market near me sells peppercorns and oil. If you can find the peppercorns you can steep them to make your own oil.
@faun look for "sichuan pepper [corn] oil" or "prickly oil", the bottle I have (http://www.asianfoodstuff.com/cart1/index.php?route=product/product&product_id=355 but that link is wholesale) is a yellow oil and doesn't mention "chili" at all
