Grease serving plate with olive oil to prevent yam from sticking onto plate.
Remove yam skin. Wash and cut into thick strips. Drain well, dust with flour and remove excess.
Heat oil and deep fry yam sticks, turning them occasionally. I had them done in 2 batches. Insert toothpick into yam to test if it is soft. Drain and set aside.
Remove oil or you can use a separate pan or wok. Heat 2 tsp of cooking oil and melt sugar, stirring continuously using low heat.
Add maltose syrup when sugar has liquefied. Stir thoroughly.
Throw in yam sticks and mix well. Turn off fire and transfer them to plate. You can add roasted sesame seeds at this point if you like. Serve your Yummy Crystallized Yam Sticks ( 麦芽糖拔丝芋头 ) with a bowl of ice water!
* Before eating, dip the hot yam sticks into ice water for the sugar coating to harden, turning them into crunchy snacks. If your yam is soft inside, and crispy on the exterior .......... Congrats, it is a success!
* Tip: Make sure you separate the yam sticks before they cool down. I made a terrible mistake by taking food shots after transferring the yam sticks onto a serving plate instead of separating them first. By the time I finished my photo shoot, the temperature of the yam sticks have already dropped and they stuck together like superglue. Lol! Well, hope you will enjoy this yummy snack as much, and have fun experimenting, sunshine!
