Kheun is a traditional Vietnamese dish made from rice flour, often served as a type of noodle. It is typically prepared by steaming the rice flour mixture in a flat tray, resulting in thin, translucent sheets. These sheets can be cut into strips and are commonly used in various dishes, including soups and stir-fries. Kheun is often enjoyed with a variety of toppings, such as shrimp, pork, or vegetables. It is a popular choice in Vietnamese cuisine, known for its chewy texture and ability to absorb flavors from accompanying sauces and ingredients.
