Combine all ingredients except the vegetable oil in a mixing bowl.

Knead until smooth and well combined. Let it rest for half an hour.

Shape into small balls of your desired size.

Heat oil in a pan over medium-low heat. Once hot, add the sweet potato balls. Press them gently to make them crispy on the outside and soft inside. Once they change color (this takes some time), remove and drain on paper towels. Ready to serve.
