Purple Sweet Potato Pie Recipe 2024

This is unlike any Purple sweet potato pie you’ve ever seen. Sweet potatoes naturally turn purple, so no food colouring is required to achieve the iconic look and delicious flavour of the original.

For a creamier, more subdued filling, use purple sweet potatoes (search for Stokes Purple, cultivated in North Carolina), which are somewhat starchier and less sweet than regular sweet potatoes. To achieve an even more subtle sweetness in the filling, we also included coconut milk. For a lovely display, top the sweet potato pie with a fluffy mound of whipped cream and a scattering of toasted coconut flakes.

What Is Purple Sweet Potatoes?

Don’t be afraid to purchase purple sweet potatoes if you come across them at the market to use in soups, stews, casseroles, and of course, pies. The anthocyanin, a kind of flavonoid that gives these potatoes, as well as cherries and grapes, their vivid colour, is what naturally gives them their purple hue. They can be used in place of regular sweet potatoes and have a creamy texture and slightly sweet flavour, though they might require a little more cooking time.

Difference Between Ube and Purple Sweet Potatoes?

Although ube and purple sweet potatoes have purple flesh, there are a few important distinctions. To begin with, ube is a yam. Sweet potatoes’ thin, silky skin contrasts with the hard, bark-like texture of yams.

Whereas purple sweet potatoes are usually a deep purple, ube flesh can range in colour from vivid light to dark purple. When cooked, ube has a nuttier flavour and a more tender texture than purple sweet potatoes, which makes it a great option for baking.
