Related Confused Words with Sweet Potato or Yam

Sweet Potato vs. Potato

Sweet potatoes and potatoes share a name, but they are distinct in their botanical families and nutritional profiles. While sweet potatoes (Ipomoea batatas) belong to the morning glory family, potatoes (Solanum tuberosum) are part of the nightshade family. Sweet potatoes offer a sweeter taste and are often orange, though they can also be purple or white. Potatoes, on the other hand, have a more earthy flavor and are commonly found in shades of brown, yellow, and red.

Yam vs. Cassava

Although yams and cassava can look similar, they come from entirely separate plant species. Yams are tubers that are typically imported from Africa and have a rough, bark-like skin. Cassava, also known as yuca or manioc (Manihot esculenta), is a staple root vegetable in tropical regions of the world and has a more smooth, waxen texture. When it comes to their use, yams are frequently boiled, baked, or fried, while cassava can be processed into tapioca and various gluten-free flours.

Yam vs. Taro

One could easily confuse yams with taro due to their shape and place in tropical agriculture. However, taro is the root of the Colocasia plant, bearing a more starchy texture and distinct nut-like flavor compared to the drier texture and neutral taste of yams. Taro also has a unique, almost hairy outer skin which is quite different from the bark-like skin of yams. It’s popularly used to make poi in Hawaiian cuisine and is also integral in many Asian dishes.
