Ingredients
  

Core Ingredients
  • 4 medium sweet potatoes (approx. 8 oz each) scrubbed clean and dried
  • 1 tablespoon olive oil or melted coconut oil for crispy blistered skin
  • ½ teaspoon coarse sea salt rubbed over skins
  • 2 tablespoons butter or cinnamon honey for serving

Method
 

Baked Whole Method (Ultra-Caramelized)
  1. Preheat oven & line pan: Preheat oven to 400°F (200°C). Line a rimmed baking sheet with aluminum foil or parchment paper (sweet potatoes release sticky sugar syrup while baking that can scorch bare pans).
  2. Scrub, dry and prick: Thoroughly scrub the sweet potatoes under water and pat completely dry. Using a fork, prick each sweet potato 6 to 8 times all around to release steam pressure during baking.
  3. Oil and salt the skin: Rub each potato with a light coat of olive oil or coconut oil and sprinkle lightly with coarse sea salt. This crisps the skin and intensifies the natural sweetness.
  4. Bake until caramelized: Place sweet potatoes directly on the lined baking sheet. Bake for 45 to 55 minutes (or up to 65 minutes for large potatoes) until a knife slides through the center with zero resistance and syrupy sugar bubbles from the fork pricks.
  5. Slit and fluff: Remove from oven, make a lengthwise slit down the center, and gently press the ends together with a kitchen towel to puff open the steaming orange flesh. Top with butter, cinnamon, or savory herbs.
