Egg noodles are served in richly flavoured dark soup stock with prawns, pork slices, fish cake slices and bean sprouts, topped with fried shallots and spring onion. The stock is made using dried shrimp, plucked heads of prawns, white pepper, garlic and other spices. Traditionally, lard is added to the soup, but this is now less common due to health concerns. A "dry" (without soup) version is also available; this version usually involves flavouring the noodles and toppings with vinegar, soy sauce, oil and chili, if desired. The dish is also usually served with freshly cut red chili slices in light soy sauce and lime juice.
