Do Purple Sweet Potatoes Taste Like Regular Sweet Potatoes?

Over 54,000 acres of sweet potatoes are harvested annually in North Carolina alone, a state known for its produce, yet many people are still unfamiliar with purple sweet potatoes. The short answer to whether purple sweet potatoes taste like regular sweet potatoes is no, they do not.

Quick Summary

Purple sweet potatoes feature a milder, often nuttier and more floral taste compared to the intense sweetness of their orange counterparts. Their texture is also drier and denser, affecting how they are best cooked.

Key Points

• Flavor is Milder: Purple sweet potatoes have a milder, more earthy, and often nuttier flavor, lacking the intense sweetness of orange varieties.

• Texture is Denser and Drier: Expect a drier, denser, and starchier texture from purple sweet potatoes, which holds its shape better when cooked.

• Requires Longer Cooking Times: Due to their density, purple sweet potatoes generally need to be cooked for a longer duration than orange sweet potatoes.

• Different Culinary Uses: Their firmer texture makes purple sweet potatoes great for savory roasting and frying, while orange sweet potatoes are better for mashing and baking into pies.

• Unique Antioxidant Content: The rich purple color comes from anthocyanins, a different antioxidant than the beta-carotene found in orange sweet potatoes.

• Complex Aroma Profile: Purple varieties can have a more complex aroma profile, sometimes with floral, wine-like, or citrus notes, according to food analysis.

A Flavor Breakdown: Purple vs. Regular (Orange) Sweet Potatoes

The most commonly encountered “regular” sweet potato in American supermarkets is the orange-fleshed variety, such as the Beauregard or Jewel. These are renowned for their high moisture content and distinctly sweet flavor, which is enhanced by their high level of the enzyme amylase that converts starches to sugars. Purple sweet potatoes, on the other hand, offer a more complex and nuanced sensory experience that differs significantly in taste and texture.

The Distinct Flavor Profile of Purple Sweet Potatoes

Purple sweet potatoes possess a unique and sophisticated flavor profile. Instead of the saccharine sweetness found in orange varieties, they offer a milder, earthier, and sometimes nutty taste. Certain varieties, like the Stokes Purple®, can have subtle, almost wine-like or floral notes, adding to their complexity. The anthocyanins responsible for their vibrant purple hue also play a role in their flavor, contributing to a more balanced and less overwhelmingly sweet character.

A Tale of Two Textures

Beyond taste, the textural difference is perhaps the most pronounced.

• Orange Sweet Potatoes: With higher moisture content, they tend to become soft, creamy, and sometimes even stringy when cooked. This makes them ideal for mashing, baking into pies, and creating creamy purees.
• Purple Sweet Potatoes: Known for being denser and starchier, they hold their shape better during cooking. This drier texture requires longer cooking times to become tender. When prepared properly, they can achieve a dense, creamy, and satisfying consistency, but will not become as moist as their orange counterparts.

Cooking Considerations and Culinary Uses

Understanding these differences is key to successful cooking. Orange sweet potatoes are a natural fit for recipes where a soft, sweet texture is desired, such as classic sweet potato casseroles and pies. Purple sweet potatoes, with their firmer texture and subtler flavor, excel in different culinary applications. Their earthy flavor pairs wonderfully with savory ingredients.

• Best for Purple: Roasting whole, frying to create crisp fries, or adding to stews and braises. They are also prized in many Asian desserts for their unique color and less overpowering sweetness.
• Best for Orange: Mashing, pureeing for baby food, baking into desserts, and any recipe where a moist, sweet outcome is desired.

Beyond the Taste: Nutritional Differences

While both varieties offer a wealth of nutrients, their primary antioxidant content differs. The high level of anthocyanins in purple sweet potatoes provides powerful antioxidant effects, which have been linked to anti-inflammatory properties and benefits for heart and eye health. Orange sweet potatoes are a fantastic source of beta-carotene, which the body converts into Vitamin A, essential for immune function and vision. Therefore, the “healthiest” choice often comes down to which specific nutrients you want to prioritize, or simply personal taste. The National Institutes of Health provides more information on the health benefits of root vegetables, including sweet potatoes.

Conclusion

Ultimately, while they share a name, purple and orange sweet potatoes are distinct in both flavor and texture. Purple varieties offer a drier, denser, and more subtly complex taste, while orange ones provide a moist and intensely sweet experience. Experimenting with both will allow you to appreciate their unique qualities and find the perfect use for each in your cooking.
