Cook the peeled and diced potatoes until soft. Alternatively one can pressure cook the potatoes.
Leave them in a colander to remove the excess water. Once cool, Mash them well.
Peel & grate the remaining raw potatoes and keep them in cold water for 5-10 minutes, so that we get the excess starch removed.
Add them into a muslin or a clean cotton cloth. Squeeze out the liquid and leave to stand for a few minutes.
Combine the cooked and raw potatoes in a large bowl with the butter, salt , pepper and herbs.
Add in enough flour to make a soft dough. Knead it for a few minutes on a floured surface until smooth. Cover & Leave for 15 minutes.
Divide the dough into equal size balls and roll out on a floured surface about 1/2 cm thick.
Shallow fry them with butter until golden brown on both sides.
