Step 1In a wok heated over high heat, add enough oil to lightly coat the base of the wok. Add the ground pork, chopped garlic and ginger, stirring until the pork is browned, 3 to 5 minutes.
Step 2Reduce the heat to low and stir in the Sichuan flavor base (add more or less depending on desired texture and heat). Cook the base with the pork to marry the flavors, then add the cornstarch slurry. Return the heat to high, and cook until the liquid comes to a boil and thickens, stirring constantly.
Step 3Pour over the prickly ash oil and chile oil and remove from heat.
Step 4In each of 8 serving bowls, ladle one-fourth cup dandan sesame sauce. Divide the noodles evenly among the bowls. Spoon over the pork and drizzle over a little black vinegar to taste. Garnish with crushed peanuts and serve immediately.
