Sai oua is a spicy pork sausage infused with an array of aromatic local herbs and spices. Popular in Laos and northern Thailand, the sausage is usually served alongside another regional favorite - sticky rice - to create a contrasting and layered dish.

The sausage is made from ground pork shoulder in a standard natural casing, mixed with some of the most commonly used herbs and spices in Lao cuisine: shallots, lemongrass, chilies, kaffir lime leaves, and garlic. Some recipes also include padaek, which is a special kind of fish sauce made in Laos.

The dish is a local delicacy, and it can be found at most eateries and street stands at all hours of the day.
