Oligodang (올리고당), or oligosaccharide syrup, is a popular Korean sweetener used as a healthier alternative to corn syrup or sugar. This clear, moderately thick syrup is derived from starches like corn or tapioca and has a clean, mild sweetness that enhances flavours without overpowering them. It's an essential ingredient in many Korean kitchens for making stir-fry sauces, marinades, and braised dishes, known as jorim (조림). Using oligodang helps to add a beautiful glaze and a subtle sweetness to dishes like spicy tteokbokki, glazed sweet potatoes (goguma mattang), or marinated beef bulgogi. Unlike regular sugar, it also helps to keep foods moist. This syrup is a staple for anyone looking to create authentic Korean dishes with the characteristic glossy finish and balanced flavour profile.
