Perfect make-ahead roast potatoes
Bring the potatoes to the boil and let them bubble away for about 7-10 minutes until the centres are still firm but the outsides are getting soft, before draining and shaking them to rough up their edges. Then open freeze them (on baking trays, covered in plastic), before bagging them up. You can cook them straight from frozen, but allow an extra 15 minutes' cooking time. Put them into the hot fat of your choice at 200/gas 6 and cook for about 60-90 minutes depending on size and whether or not you defrosted them first. Turn them once during cooking.
