Boil the potatoes for 15-20 minutes until soft and tender.
Roughly mash the potatoes and leave aside.
In a pan, fry the onions and cumin seeds until onions are soft and translucent
Combine all filling ingredients together until evenly mixed and mushy and leave to cool.
Next make the pastry by combining the flour water and salt together in a large bowl.
Add the water, a little at a time, stirring with a wooden spoon, until a moderately soft, yet sticky dough results.
Transfer the dough to a flat surface dusted with flour and knead, adding flour, a little at a time until the dough is no longer sticky.
Divide the dough into 7 balls and roll out into until roughly 3mm thick.
Cut each circle in half.
Make a ‘glue’ by mixing together some flour and water to attain a runny yet gloopy, white paste
Brush the straight edge of the pastry bits with the glue and then fold into a cone.
Spoon roughly 1 tbsp of the filling into each cone and seal the open edge with more glue, pinching to ensure the sides are stuck down.
Lay the samosas onto a greased baking tray and brush the surfaces with oil.
Bake at 200C for 25 minutes, turning halfway for a more even finish.
