Thai Fried Sweet Potato Balls (Khanom Kai Nok Krata)
Chef Lyn
Crispy on the outside and chewy inside, these Thai fried sweet potato balls — Khanom Kai Nok Krata — are a beloved street snack made with mashed sweet potatoes, tapioca flour, and coconut milk.
Wash, peel, and cut the sweet potatoes into medium pieces. Steam until fully cooked, then mash while still hot until smooth.
Transfer the mashed sweet potato to a mixing bowl. Add the tapioca flour, sugar, and salt. Mix until crumbly.
Gradually add coconut milk and knead (or mix) until the dough is smooth and uniform. Test by rolling a small ball — it should hold its shape without being too dry or sticky.
Roll the dough into small bite-sized balls and set aside.
Heat oil in a deep pan over medium heat. Once hot (but not too hot- around 160–170°C / 320–340°F), gently add the balls without stirring at first.
When the surface begins to set, gently stir to prevent sticking. Use a strainer or spatula to gently press the balls, helping them puff up, become hollow inside, and turn crisp.
Fry until golden brown and evenly crisp. Remove and drain on paper towels before serving.
