Cut the potato and cauliflower into small pieces. If making samosas you will need to cut the vegetables into roughly pea sized cubes, but if eating the potato and pea as a curry you can keep the vegetables slightly larger.
Heat some oil in a pan, then add the cumin seeds and stir for a few seconds until brown. Add the potatoes, cauliflower, chopped chillies, grated ginger and powdered spices, stirring continuously.
Next add a little water and cook slowly on low heat stirring occasionally until the vegetables are cooked.
Finally, add a handful of peas and sultanas and cook for a couple of minutes more.
To make the samosas Roll out a packet of puff pastry.
Cut into square shapes and fill each square with cold samosa filling.
Seal the edges by pinching then cook for about 15 minutes at 200C until golden brown.
