Preheat the air fryer at 180 degree Celsius 5 minutes before frying
Cut the Yam into very thin Strips
Drizzle 2 tablespoons of oil over the Yam and ensure all the Yam strips are coated with oil
Air fry for 8 mins or until golden brown at 180 degree Celsius (Pull out the basket and shake halfway during frying (or use a tong to "stir") so that any overlay bits will be air fried too)
Divide the Yam into several batches for frying (Do not overcrowd the frying basket)
When done, drizzle 1 tablespoon of truffle oil and sprinkle truffle salt over the Yam fries
Toss until the fries are well coated with salt and truffle oil
Cool and store in airtight container
