After the taro balls are cooked, be sure to immediately run them under cold water several times until they are completely cooled. It's even better to soak them in ice water for about two to three minutes if you have it available. Then be sure to drain the taro balls.
If you need to keep it for a shorter period of time, say twenty-four hours or so:
Method 1: After the taro balls have passed through the cold water, wrap a layer of starchy sesame seeds around the outside of the taro balls and then pack them in a plastic box and put them in the refrigerator to keep them fresh, and then when you need to eat them, take them out and cook them again for a little while.
Method 2: After the taro ball water, and then put into a plastic box with clean ice water, and then stored in the refrigerator in the fresh cupboard.
If you need to keep them for a little longer, say three or four days:
Method 1: Coat the taro balls in a layer of sesame starch, then portion them out by volume in a plastic bag and store them in the freezer.
Method 2: Arrange the taro balls one by one on a tray and then place them in the freezer. When the taro balls harden, take them out and put them in a plastic box, then put them in the freezer again.
Suggestion: Cooked taro rounds saved and then eat the taste will be worse, the preservation of time is also very short, while the raw frozen preserved for a month or two are no problem, each time you eat how much to cook how much, so that there will be no waste, the taste will be much better.
