Szechuan chicken comes from the region of Sichuan in China and is meant to be pretty spicy. Szechuan cuisine is known for using strong flavors and especially Szechuan peppercorns, which have a very distinct and have a numbing effect. We recommend using them in this dish, but if you can't find them black peppercorns can be used, but of course won't have quite the same flavor. Most of the heat comes from the chiles so if you're sensitive to heat, feel free to cut back on some of them.
