What Are Purple Sweet Potatoes?
Origins and Popular Varieties
Purple sweet potatoes have their roots in tropical regions like Hawaii, Okinawa, and the Philippines. These tubers, often called “Ube” or Okinawan sweet potatoes, are celebrated for their vibrant purple color, which comes from anthocyanins—powerful antioxidants that also give blueberries and red grapes their hue. Two of the most popular varieties are the Okinawan sweet potato, known for its creamy texture, and the Stokes purple sweet potato, which has a denser consistency and nutty flavor.
Nutritional Benefits of Purple Sweet Potatoes
Purple sweet potatoes are packed with nutrients that make them a valuable addition to your diet. They’re an excellent source of complex carbohydrates, providing energy without spiking your blood sugar. Rich in vitamins A and C, they support immunity, skin health, and vision. Their high fiber content aids digestion, while the anthocyanins help fight oxidative stress and inflammation. Including purple sweet potatoes in your meals can lower the risk of chronic diseases like heart disease and diabetes, according to research.
Do Purple Sweet Potatoes Have to Be Peeled?
When to Peel
Peeling purple sweet potatoes is a matter of preference and practicality. In recipes where a smooth texture is key, such as mashed potatoes or desserts, peeling can help achieve the desired consistency. Additionally, if the skins are tough, damaged, or particularly dirty, peeling them ensures a more appealing final dish. Use a vegetable peeler or a sharp paring knife to remove the skin efficiently.
When to Skip Peeling
If you’re looking for maximum nutrition, consider leaving the skin on. The skin of purple sweet potatoes is not only edible but also rich in fiber and antioxidants. Keeping the skin intact saves preparation time and boosts the nutritional profile of your meals. To prepare them with the skin, simply scrub the potatoes thoroughly under running water using a vegetable brush to remove any dirt. When roasted or steamed, the skin can add a delightful texture and flavor to your dish.
