Wash the sweet potatoes thoroughly.

Peel the sweet potatoes and cut them into bite-sized pieces.

Soak the sweet potato pieces in water for 10–20 minutes to remove starch, then drain.

Pat the sweet potatoes dry with a kitchen towel.

Place the sweet potatoes in a plastic bag, add 2 tbsp olive oil, and mix well.

Arrange the sweet potatoes in the air fryer and cook at 200°C for 10 minutes. Flip and cook for another 7 minutes.

In a frying pan, combine 2 tbsp raw sugar, 3 tbsp water, and 2 tbsp corn syrup.

Simmer on low heat until the sugar is fully dissolved. Avoid stirring; let it dissolve naturally.

Add the cooked sweet potatoes to the syrup and mix gently on low heat until well coated.

Sprinkle sesame seeds or black sesame seeds on top.
