Ingredients
Main Ingredients (2 servings)
- Sweet Potatoes 300g
- Frying Oil (enough to submerge sweet potatoes)
Seasonings
- [A] White Sugar 4 tbsp
- [A] Water 2 tbsp
- Salt a pinch
- Black Sesame Seeds (toasted) 1 tsp
Steps
- Cut 300g of sweet potatoes into bite-sized wedges.
- Soak the cut sweet potatoes in water for about 5 minutes to remove excess starch.
- Drain the sweet potatoes in a colander and pat them dry with paper towels.
- Arrange the dried sweet potato pieces in a frying pan.
- Pour in frying oil to cover the sweet potatoes and heat over medium-high to high heat.
- Once the oil is hot and large bubbles start to form, reduce heat to medium. Fry, turning occasionally, until golden brown all over. Key tip: Cooking slowly from a low temperature ensures they become fluffy and sweet inside. The estimated frying time is about 10 minutes. Check for doneness by inserting a chopstick.
- Transfer the fried sweet potatoes to paper towels to drain excess oil.
- In a clean frying pan, combine 4 tbsp of white sugar and 2 tbsp of water. Key tip: Use granulated sugar or superfine sugar for a white finish.
- Bring the sugar and water to a boil over high heat. The syrup is ready when the bubbles become smaller and it thickens enough to coat the tip of a chopstick.
- Add the fried sweet potatoes, 1 tsp of black sesame seeds, and a pinch of salt to the thickened syrup and toss to coat evenly. Key tip: Adding a small amount of salt enhances the sweet and savory flavor, making it even more delicious.
- Once coated, remove from heat and continue stirring until the sugar crystallizes and turns white. Key tip: Removing from heat and lowering the temperature allows the sugar to recrystallize, creating a white coating around the sweet potatoes.
- Once the sugar has crystallized and turned white, transfer to a serving dish. Enjoy the crispy exterior and fluffy interior!
