Want to have a good sweet dessert from sweet potatoes? This is the easy way to do it. What you need is sweet potatoes, ginger, and sugar. Use palm sugar for this if you can get it. However, if you do not have it, you may use any kind of sugar.
Determine for how many people you want to serve the dessert. For example, if you want to cook for 3 people, 2 lbs sweet potatoes will be enough. Wash the sweet potatoes with warm water and peel them.
Prepare a ginger. A half finger size of ginger will be enough if you don't want it to hot, but if you like a hot soup, you may used a finger size. Slice the ginger into a pieces.
Boil the sweet potatoes and ginger with water. Make sure all the sweet potatoes are under the water. For 2lbs, 4 glasses of water should be good enough. It should take about half an hour to be ready.
After the water boils, add the sugar into the water. If you used "palm sugar" you should shiver it first, to make it easy to melt on the water. The amount of sugar is depend on how sweet you like (5 - 7 spoons will be enough or a half-cut for palm sugar). Add more sugar if you want to serve the dessert with ice.
You may choose to serve it hot or serve it with ice.
