Sichuan pepper, also known as Szechuan pepper, Chinese prickly ash, Chinese pepper, Mountain pepper, and mala pepper, is a spice commonly used in Sichuan cuisine in China, in Nepal, and in northeast India. Despite its name, Sichuan pepper is not closely related to black pepper or chili peppers. It is made from plants of the genus Zanthoxylum in the family Rutaceae, which includes citrus and rue. You can stir-fry them or braise them. Stir-frying is the simplest. Pour some cooking oil into a wok or a frying pan and let it heat over the stove to make spicy Sichuan oil. Add some chili peppers to enhance the heat and flavor. Toss the Szechuan peppercorns while you’re cooking them. The stir-frying technique is a Chinese innovation and is very common for roasting these peppercorns. Braising is another technique used especially when cooking meat. In braising, add Sichuan peppercorns to the meat in a frying pan.
