They are denser and creamier than their orange counterparts, with flavors ranging from sweet to nutty. When cooked, their color intensifies, making them a visually appealing addition to various dishes.
This distinct color and delicious taste often lead to the question: do purple sweet potatoes taste different? The answer is yes; their rich, subtle flavors and eye-catching presentation set them apart.

Cooking and Recipes

Fries: Another popular recipe is purple sweet potato fries. These are made by cutting the potatoes into strips, tossing them with oil and seasonings, and baking until they are crispy. They serve as a colorful and healthier alternative to regular fries.
Soups and Stews: Their robust texture also makes purple sweet potatoes a great addition to soups and stews. They add thickness and a burst of color, enhancing the visual appeal and nutritional profile of the dish.
