Szechuan beef is a perfect recipe for the spicy food lover, with thinly sliced beef stir fried in a steaming hot pan, served up with chili peppers of your choice. The key is the homemade Szechuan sauce, which you can whip together in very little time, along with some wonderfully vibrant and spicy flavors characteristic of Sichuan cuisine. Szechuan peppercorns in particular add a unique flavor and tongue-numbing quality, which greatly compliments the expansive umami of the Szechuan sauce.
