Sweet potatoes and yams have quite a few differences when it comes to the way they’re grown, their taste and overall nutritional profile. First, yams are part of the Lily family of origin while sweet potatoes are part of the morning glory family. When it comes to taste, sweet potatoes tend to be more moist while yams are on the drier side. Additionally, sweet potatoes taste sweeter, while yams have a more starchy taste and texture. In terms of their nutritional profile, sweet potatoes contain more vitamin A, beta carotene and are lower in both calories and carbohydrates, while yams are slightly higher in fibre, potassium and vitamin C. Both are nutritious options, but it’s important to differentiate between the two when looking for either option at the grocery store. While either sweet potatoes or yams can be used in this recipe, you will likely get better results with sweet potatoes due to their naturally sweeter taste and moist texture.
