500gm of sweet potatoes.. boil and mash .. add a little salt.. (mash like making mash potatoes.)
1 cup of plain flour
1.Add the plain flour bit by bit while you mix well till it is form to a nice dough
2. Using a ice cream scoop for measurement... and form it like a ball and press it slightly flat and using the back of the wooden spoon to form a hole and a shape like a donut.... yeah!!
3.Heat the wok ... deep fry method... fry the donut till crispy and brown (do not put the fire on high, medium will do .. or else the donut will get burn easily)
4. Place the donut on the plate and sieve some icing sugar or homemade grind sugar on top....
PS: You can use the blender to grind the normal sugar.. sieve over the kue keria
if possible buy the light yellow colour sweet potato it is more firm.
