Step-by-Step Instructions
Step 1. Prepare the Sweet Potatoes and Dough
- Wash and steam sweet potatoes for 20 minutes, or boil them for the same duration. Check for doneness by inserting a fork; if it comes out clean, they're ready.

- Add the cooked sweet potatoes to a mixing bowl and mash into a paste using a mixer on low speed or by hand.
- Add the remaining ingredients (tapioca starch, all-purpose flour, baking powder, sugar, and salt) and gently fold everything together using a rubber spatula.




- Mix on low speed until everything is well combined (about 2 minutes).
- Lightly flour your hands and roll the dough into 3/4-inch balls.


Step 2. Shape and Fry the Balls
- Heat cooking oil in a frying pan over medium-low heat. Do not use high heat.
- Fry the sweet potato balls for about 3-6 minutes, or until golden brown, gently turning them to ensure even cooking.


Step 3. Drain Excess Oil

FAQs
1. Can I use regular potatoes instead of sweet potatoes?
While you can try, regular potatoes lack the natural sweetness and moisture of sweet potatoes, resulting in less flavorful and potentially drier balls. Sweet potatoes are highly recommended.
2. How do I store leftover Khanom Kai Kwa?
Store them in an airtight container at room temperature for up to 2 days. For longer storage, freeze them for up to a month. Reheat in the oven or air fryer before serving.
So there you have it – your very own batch of crispy, delicious Thai sweet potato balls! Enjoy these delightful treats as a snack, dessert, or a fun addition to your next party. Happy cooking!
