How to Make Khanom Kai Nok Krata
Detailed Step-by-step Method:Print these instructions >
To make the Thai sweet potato balls we need about 2 cups of mashed sweet potato or yam. In Thailand we usually steam the potatoes to cook them, but you can boil, bake, or even microwave them. The goal is to get nice smooth mashed or whipped potato.
These will take about 20 - 30 minutes by steaming. Check them with a fork to be sure they are very soft.
Peel the potatoes and cut away the rough ends and any hard spots.
Mash or whip the potatoes thoroughly however you normally do it. I like to use my hand blender so I can measure the whipped potato at the same time.
Now just add in the tapioca starch, sugar, salt, and cinnamon.
Stir it in well to make a thick and pasty batter.
Dust your hands well with all purpose flour, spoon about 1 teaspoon of the batter onto your hand, then roll it into a small ball. This takes a little practice and experimenting with the right amount of flour, so don't worry if the first one comes out wrong. The batter is quite sticky, so keep putting flour on one hand as you continue to roll. Eventually you will have a ball that is not sticky on the outside. Roll all the balls and lay them on a pan dusted with flour or lined with wax paper.
I use a big pot to deep fry in so the oil doesn't splatter. If you have a deep fryer that will be even better. It's important to keep the temperature low, so only at 150° C or about 300° F. This is on the low end of the temperature normally used for frying. The batter has a lot of sugar so they can easily burn if too high. They need to cook for at least 5 minutes and still be golden brown. Fry just a few at a time so they aren't crowded and stir continuously with a rolling motion so they roll around and never sitting still.
Remove them from the oil and let drain on a wire rack or paper towels.
Dust a light coating of powdered sugar over them while still very warm, then allow to cool some more.
For the best flavor and texture, serve while still a little warm.
