The heart of Vegetarian Ma Po Tofu lies in its signature sauce. Create a flavorful blend by combining fermented bean paste, soy sauce, garlic, ginger, and Sichuan peppercorns. Adjust the spiciness to your liking by adding chili oil or chili flakes. The sauce brings a harmonious balance of heat, umami, and richness, infusing the tofu and vegetables with a tantalizing flavor profile.
