What to get ready

• Sweet potato 800 g
• Sugar 200 g
• Soy sauce 20 ml
• Rice vinegar 20 ml
• Black sesame 32 g
• Oil 800 ml

Method

1. 1 Cut the sweet potatoes into slanted slices, soak them in water for 10 minutes, then pat them dry.
2. 2 Fry the potatoes at 150 degrees for 8 minutes until they are cooked through and tender.
3. 3 Remove from the oil, then increase the oil temperature to 180 degrees and fry again for 1 minute until the crust is crispy.
4. 4 Cook sugar with a little water, soy sauce, and vinegar until the sugar syrup thickens and turns a golden brown color.
5. 5 Pour the potatoes into the pan and stir quickly until evenly coated, sprinkle with black sesame seeds, then spread them out on a tray to prevent them from sticking together.

With an appliance

• Air fryer 34 min

  Replace steps 2 and 3: spray oil on the potatoes, fry at 170 degrees for 14 minutes, then increase to 200 degrees for another 4 minutes, flip at the 8th minute; step 5 still involves quickly stirring with the sugar syrup in the pan.
