Pad Thai is a style of cooking and is one of the national dishes enjoyed in Thailand. To make this kosher-prepared dish, a base of cooked rice noodles is stir-fried until tender. Thai fish sauce is added to the noodles to brighten their flavor. The bite of fiery red chili peppers is balanced by sweet tamarind juice. Chicken is usually added to the noodles to make a more complete meal. Tofu can be substituted for the chicken to make the Pad Thai a vegetarian dish. Crushed peanuts give a unique crunch while coriander and lime juice help season the dish.
