While they share a sweet and starchy nature, these two tubers possess distinct characteristics that set them apart. This comprehensive guide delves into the world of sweet potatoes and Korean yams, exploring their differences in appearance, nutrition, flavor, and culinary applications.

Appearance

Sweet potatoes, known scientifically as Ipomoea batatas, boast a wide range of skin colors, from deep orange to cream or purple. Their flesh is typically orange or white, with a smooth, moist texture.

Their flesh is typically white or light brown, with a slightly drier texture.

Both sweet potatoes and Korean yams are nutritional powerhouses, but their nutrient profiles differ slightly. Sweet potatoes are particularly rich in vitamin A, providing over 100% of the daily recommended intake in a single serving. They also contain significant amounts of vitamin C, potassium, and fiber. Korean yams are a good source of vitamins B6 and C, as well as potassium and manganese.
