Murasaki sweet potatoes are a distinctive and increasingly popular variety of sweet potato, known for their vibrant purple skin and creamy white interior. Gaining attention in recent years, especially at specialty retailers like Trader Joe’s where they are often featured as a seasonal offering, Murasaki sweet potatoes are making a mark in the culinary world. While they share some characteristics with traditional sweet potatoes, such as their sweetness, their unique appearance and flavor set them apart. Whether you’re already familiar with these purple beauties or encountering them for the first time, here’s everything you need to know about Murasaki sweet potatoes and how to add them to your meals.
What Are Murasaki Sweet Potatoes?
Murasaki sweet potatoes, despite often being labeled as “Japanese sweet potatoes,” are a relatively new variety developed in Louisiana. The name “Murasaki” comes from the Japanese word for “purple,” referring to the striking purple skin of the tuber. However, unlike other purple sweet potato varieties, the flesh of the Murasaki sweet potato is creamy white rather than purple. Originally developed in 2001 by the Louisiana Experiment Station and officially released to growers in 2008, Murasaki sweet potatoes have roots in Louisiana but are primarily grown in California, where the climate is best suited to their needs.
Easily identifiable by their vibrant purple skin, Murasaki sweet potatoes differ from the more common orange-fleshed varieties in both texture and flavor. The flesh is typically starchier and drier, offering an earthy taste and a more subtle sweetness compared to the sugary flavor of other sweet potatoes. If you’re looking for a sweet potato with a unique, less sugary flavor, the Murasaki variety is a perfect option.
What Does Murasaki Sweet Potato Taste Like?
Murasaki sweet potatoes have a distinct flavor that sets them apart from their orange-fleshed counterparts. With a nutty, earthy taste and subtle notes of brown sugar and vanilla, they aren’t as sweet as traditional sweet potatoes, making them a great choice for those who prefer a more savory profile. Their higher starch content (around 30 to 32 percent dry matter) gives them a firmer, drier texture when cooked, similar to that of regular potatoes, as opposed to the creamy consistency of typical sweet potatoes.
Thanks to their less sugary flavor, Murasaki sweet potatoes are ideal for savory dishes where their nutty undertones can really stand out. They can be roasted, mashed, or pureed, and they pair wonderfully with a variety of seasonings and spices that enhance their earthy taste.
Murasaki Sweet Potato vs. Common Sweet Potato
Although Murasaki sweet potatoes and traditional sweet potatoes may seem alike at first, several key differences set them apart. The most noticeable distinction is the skin color: while common sweet potatoes like Beauregard and Jewel have orange skin and flesh, Murasaki sweet potatoes boast a striking purple skin with white flesh.
In terms of texture, Murasaki sweet potatoes are drier and starchier compared to the moist, creamy texture of their orange-fleshed counterparts. When cooked, their flesh is firmer and drier, resembling a regular potato more than a classic sweet potato. If you prefer a firmer bite with less softness or gooeyness, Murasaki sweet potatoes are the perfect choice.
The flavor also varies significantly. Orange-fleshed sweet potatoes are known for their sweet, sugary taste, while Murasaki sweet potatoes offer a more subtle, nutty sweetness with earthy undertones. This makes them an excellent option for those who enjoy a more complex flavor and provides greater versatility for savory dishes.
Where to Buy Murasaki Sweet Potatoes
Murasaki sweet potatoes are considered a specialty item, so they might not be available at every grocery store. However, if you shop at Trader Joe’s, you’re in luck, as they often carry these sweet potatoes, especially during their peak season from early fall to winter. Aside from Trader Joe’s, you might also find Murasaki sweet potatoes at other grocery chains, health food stores, or specialty markets that offer organic and unique produce.
Since they are mainly grown in California, Murasaki sweet potatoes are most commonly found on the West Coast, though availability can extend to other regions depending on the time of year. When purchasing Murasaki sweet potatoes, look for firm, smooth ones with vibrant purple skin. Avoid any with signs of softness or wrinkling, as these may be past their prime.
