Boil the potatoes for 5 mins.
Meanwhile, heat the oil in a frying pan
and gently fry the onion for 8 mins.
Add the garlic and spices, then fry for
2 mins more.
Drain the potatoes and tip into the
onion mix. Turn up the heat and shake
the potatoes around so that they are all
covered. Cook for 10 mins more until
tender, then serve with soured cream,
sprinkled with a little cayenne.
