Sweet Potato vs. Yam: Usage and Examples
When it comes to using sweet potatoes and yams in our cooking, we have a variety of options due to their unique flavors and textures.
Sweet potatoes tend to be more versatile and are commonly used in both savory and sweet dishes. They’re moist and sweet which makes them a favorite for incorporating into:

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.
