Wash and quarter the potatoes, then dab with kitchen paper. Mix well in a large bowl with the garlic oil, curry, paprika, chilli, salt and pepper and place on a previously greased baking sheet. Add the rosemary sprigs.
Bake for about 45 minutes until the potatoes are cooked through.
Serve with the sour cream and a fresh green salad. A cucumber salad also goes well.
