Recipe

Mix 2 tablespoons of sugar into 1.5L of water to make a sugar solution that prevents browning of the sweet potatoes.
Peel the sweet potatoes using a peeler, then immediately submerge them in the prepared sugar water to prevent darkening.
Trim off both ends of the sweet potatoes, cut them lengthwise into four equal pieces, then slice them into thick pieces about 6–7mm thick.
Briefly rinse the sliced sweet potatoes in the sugar water, then immediately drain them through a colander to remove excess moisture.
Place the sweet potatoes in a steamer once the water has started to boil and steam rises. Cover tightly and steam over high heat for 8 minutes.
Using tongs, carefully remove each piece and arrange them on a tray without overlapping. Let them rest for 5 minutes to cool slightly and release moisture.
Place the sweet potatoes on the dehydrator tray and set the temperature to 70°C for the first 2 hours of drying.
After 2 hours, reduce the temperature to 40°C and continue drying for an additional 2 hours to achieve a soft yet chewy texture.

Peel and slice the sweet potatoes thickly, then briefly soak in sugar water to prevent browning.
Steam in a steamer with rising steam over high heat for 8 minutes, then let cool slightly.
Dehydrate in a food dryer at 70°C for 2 hours, then lower the temperature to 40°C and dry for another 2 hours to finish.

Cooking tips

Before cutting, make shallow incisions along the surface and press down firmly—this helps prevent injury and makes handling safer.
Do not leave the sweet potatoes in the sugar water for too long, as starch may leach out and reduce chewiness; just briefly rinse and drain.
Avoid drying at high temperature throughout—this causes the sweet potatoes to become hard and stiff. The key is to first remove surface moisture at high heat, then finish drying at low temperature.
