Pad Thai is a Thai noodle stir fry dish that is one of the most popular menu items at Thai restaurants around the world. It is made with thin, flat rice noodles that are stir-fried with eggs and chopped firm tofu, flavored with tamarind juice, fish sauce, dried shrimp, garlic, shallots, and palm sugar, and served with lime wedges and often crushed roasted peanuts. Pad Thai almost always has bean sprouts, garlic chives, scrambled egg, and a protein, with the most popular being chicken or prawns/shrimp. Other vegetables like shredded carrots, preserved radish, and raw banana flowers may also be added. Pork or beef can also be used as a protein. To make vegan or vegetarian Pad Thai, the egg can be left out and the fish sauce can be substituted with more soy sauce. The noodles used in Pad Thai are flat dried rice noodles that can be found in everyday supermarkets.
