Mix the sweet potato with all the other ingredients. You should get sticky mixture.
Heat some oil in wok or frying pan. When the oil is hot, add small spoonfuls of the mixture, flatting them slightly with the base of the spoon.
Fry for a minute or so, then turn them over and fry until golden and crispy.
Drain them on paper kitchen towels.
Baked version: Preheat the oven to 200°C. Line a baking tray with baking paper.
Add dollops of the mixture, then flatten them slightly with the spoon. Spray each with a little oil, then bake them for 10 minutes or so until crispy and golden.
Serve the fritters warm or at room temperature.
