Sai Ua is a traditional Northern Thai sausage known for its bold and aromatic flavors. It typically consists of ground pork mixed with a blend of Thai herbs and spices such as lemongrass, kaffir lime leaves, garlic, shallots, and chilies. These ingredients give Sai Ua its distinctive taste, which is both spicy and fragrant. The mixture is then stuffed into casing, often made from natural materials like hog intestine, and grilled or roasted until cooked through. Sai Ua is commonly served as a snack or appetizer in Thailand and is enjoyed for its savory and spicy profile.
