  • 500 g sweet potato 
  • 2 tbsp water
  • 1 tbsp maple syrup
  • 3 tbsp sugar
  • black sesame seeds, for garnishing


  1. Wash the sweet potatoes and peel the skin with a potato peeler.

  2. Cut the sweet potatoes into 1-inch chunks and place them into a bowl with water to soak for 10 minutes to release excess starch. Rinse the potatoes 2 to 3 times after.

  3. Bake the sweet potatoes in the oven at 385 degrees F for 18 to 20 minutes.

  4. In the meantime, prepare the syrup. Add the water, maple syrup and sugar in a small pan over medium heat. Swirl the pan until the sugar completely dissolves. Do not stir the syrup as this causes the sugar to dissolve unevenly and create clumpy sugar clusters.

  5. Once the syrup turns slightly brown, add in the potatoes and toss until evenly coated.

  6. Transfer the sweet potatoes onto some parchment paper and sprinkle with toasted black sesame seeds.

  7. Allow them to cool and enjoy!
