Sweet Potato or Yam?
Did you know? Sweet Potatoes and yams are completely different vegetables.
The orange tapered potatoes commonly called yams are in fact sweet potatoes, while many people have probably never tried a yam before. Yams are brown with a bark-like skin and are not very common in North America. Yams can also grow to be much bigger than sweet potatoes. There are a couple different varieties of sweet potatoes which vary in colour such as rose coloured skin with orange flesh, pale copper/tan skin with white flesh, red skin with dry white flesh, as well as purple skin and flesh.
The nutrition profiles of yams and sweet potatoes are similar, however yams are starchier, while sweet potatoes are sweeter. Sweet potatoes have more Vitamin A while yams have more Vitamin C and potassium. Yams and sweet potatoes can both be prepared by roasting, steaming, boiling or frying. Substituting yams in a sweet potato dish would be like using potatoes instead of sweet potatoes in the recipe—it would work, but the end result would taste very different.
