Understanding Purple Sweet Potatoes

What are Purple Sweet Potatoes?

Purple sweet potatoes are a variety of sweet potato known for their stunning purple flesh and skin. Native to regions such as Asia and South America, these potatoes are now enjoyed globally for their rich flavor, dense texture, and nutritional benefits.

Purple sweet potatoes are often confused with other varieties like ube or Okinawan sweet potatoes. However, they stand out due to their unique earthy-sweet taste and vibrant hue, which comes from anthocyanins, the same antioxidants found in blueberries.

Whether you peel them depends on how you plan to use them:

  • Roasting or Boiling: Keeping the skin adds a slightly crispy texture and extra nutrients.

Benefits of Keeping the Skin On

Choosing not to peel purple sweet potatoes offers several advantages:

  3. Better Texture: The skin provides a delightful contrast, especially when roasting or baking.
  4. Less Food Waste: Using the whole potato reduces unnecessary waste.

While leaving the skin on is generally beneficial, there are certain situations where peeling may be preferred:

  • Recipes Requiring Smooth Consistency: For dishes like mashed potatoes, peeling ensures a creamier texture.
  • Damaged or Dirty Skin: If the skin appears tough, bruised, or dirty even after cleaning, peeling might be necessary.
  • Personal Preference: Some people simply prefer the texture and appearance of peeled potatoes.

    • Preheat your oven to 400°F (200°C).
    • Scrub the purple sweet potatoes thoroughly to remove any dirt.
    • Cut them into wedges or rounds.
    • Drizzle with olive oil, season with salt and herbs, and place them on a baking sheet.
    • Roast for 30-40 minutes until tender and crispy on the edges.
  2. Boiling
    • Rinse the potatoes well, leaving the skin intact.
    • Cut them into halves or cubes to reduce cooking time.
    • Place them in a pot of boiling water and cook for 20-25 minutes or until fork-tender.
    • Boiling with the skin on helps prevent nutrient loss and keeps the potatoes firm.
  3. Steaming
    • Clean the potatoes thoroughly and cut them into chunks if desired.
    • Place them in a steamer basket over boiling water.
    • Steam for 20-30 minutes until soft. Steaming preserves the flavor and nutrients.

    • Scrub the potatoes clean, pat them dry, and pierce the skin with a fork to allow steam to escape.
    • Bake for 45-60 minutes until tender.
    • Enjoy as-is or slice open and add your favorite toppings.

By leaving the skin on, these methods ensure the sweet potatoes maintain their vibrant color, flavor, and nutritional value.

Proper Peeling Techniques

If you prefer peeled purple sweet potatoes for specific recipes, here’s how to peel them effectively:

  1. Rinse First
    • Begin by washing the potatoes thoroughly under running water to remove dirt or debris.
  2. Boil Before Peeling (Optional)
    • Boiling the potatoes for 5-10 minutes can loosen the skin, making it easier to peel. Allow them to cool slightly before handling.
  3. Using a Peeler
    • Use a sharp vegetable peeler to remove the thin layer of skin. Start from one end and work your way around the potato.
  4. Cutting Method
    • If peeling with a knife, carefully slice off the skin in thin strips to minimize waste. Hold the potato firmly for safety.

Cleaning Purple Sweet Potatoes Effectively

For those leaving the skin on, proper cleaning is essential to remove dirt, residue, or impurities. Here’s the best way to clean them:

  • Use a Vegetable Brush: Scrub the potatoes gently under running water using a vegetable brush or clean cloth.
  • Avoid Soap: Never use soap or detergents, as they can leave unwanted residue on the skin.
  • Inspect for Damage: Check for bruises or blemishes and trim those parts off with a knife.
  • Soak (Optional): Soak the potatoes in cold water for 10 minutes if they’re particularly dirty, then scrub again.

Proper cleaning ensures your purple sweet potatoes are safe to eat and ready for cooking, whether peeled or not.
