What Are Japanese Purple Sweet Potatoes?
Before we get to the recipe, let’s talk about the star of the show: Japanese purple sweet potatoes. Known as murasaki imo in Japan, these beauties have reddish-purple skin and a vibrant purple flesh that stays bold even after cooking.
Unlike their orange cousins, Japanese purple sweet potatoes have a slightly drier, starchier texture and a nutty, earthy flavor. They’re less sweet than regular sweet potatoes, making them perfect for both savory and sweet dishes.
Fun fact: These potatoes originally came from Central and South America but found their way to Japan via China in the 17th century. Today, they’re a staple in Japanese cuisine, used in everything from tempura to desserts.
