Want to know how to make the perfect roasted potatoes?
Nigella crisps hers in duck fat, Delia prefers lard. Jamie Oliver ‘chuffs’ his up in a pan with lemon and rosemary, while Heston Blumenthal insists on using a rare Scottish spud.

But stand aside, celebrity chefs. For not a lot of people know that the person who serves the best roast potatoes is Michael Caine.

So what’s his secret? Caine swears by soaking parboiled potatoes in cold extra virgin olive oil before cooking, allowing the fat to be absorbed deep into the spuds’ flesh.

He then pops them onto a baking tray and into a hot oven for an hour and, low and behold, they emerge with a honeycomb coating that is deep, crisp and even.
