Heston's roast potatoes >

 ‘A great roast potato should be crisp and crunchy on the outside, and soft and fluffy on the inside, with hints of garlic, rosemary and thyme – exactly what this recipe delivers.’ Heston Blumenthal

Michel Roux Jr’s roast potatoes >

'The key to a good roast potato is simple: use a floury variety, boil until they’re just soft on the outside but not quite cooked through, give them a good shake to fluff the edges, then roast till golden and crisp.'

Michel Roux Jr is chef-patron of Le Gavroche in London
