If you like your food spicy, this recipe is for you. These scallion pancakes are served with a spicy Szechuan sauce that adds a fiery kick to the dish. The sauce is made from a combination of Szechuan peppercorns, chili oil, soy sauce, and vinegar. Drizzle the sauce over the pancakes or serve it on the side for dipping. The heat from the sauce pairs perfectly with the savory scallions, creating a flavor explosion in every bite.
