Dan Dan Noodles is a dish that hails from the Sichuan province in China. You might have heard of Sichuan because that’s where those crazy chilli peppercorns that create an almost-numbing sensation are from. Are they in this recipe? YOU BETCHA! Dan Dan noodles are traditionally topped with chilli oil, delicious umami noodle sauce, crumbled pork mince cooked with preserved mustard stems and some sort of steamed or blanched dark leafy greens.
