Wash the vegetables and herbs. Peel the garlic, ginger and potatoes. Chop the coriander, chilli, ginger and raisins. Press the garlic through a press. Cook the potatoes in salted water until they are soft, then drain them and allow them to steam. Mash the potatoes and leave them to cool. Mix potatoes with lemon juice, raisins, coconut flakes, coriander and cornflour, and season with spices. Divide the dough into 12 portions and shape them into flat patties. In a frying pan, fry the patties on both sides in the rapeseed oil until they are golden brown.
