Ingredients

  • 1kg/2¼lb charlotte potatoes
  • 1 tbsp salt
  • 300g/10½oz cold butter
  • warm milk

Instructions

  • Peel the potatoes and cut them into 2.5cm (1in) slices. Run the slices under cold water to wash off surface starch. Heat a large pan of water until it reaches a temperature of 80C/175F (you'll need to use a good-quality heat thermometer, with the probe placed in the water. Add the potatoes and simmer for half an hour being careful to maintain the temperature at 70C/160F. Drain the potato slices and run them under cold water until completely cool.
  • Rinse the pan and refill with cold water. Salt the water and bring it to the boil, then lower to a simmer. Add the cooked, cooled potatoes and cook until soft. Drain the potatoes, then place them back in the pan. Shake the pan over a gentle heat to get rid of any remaining water.
  • Tip the potatoes into a ricer and rice the potatoes over a bowl containing the cold butter. Push the buttery riced potatoes through a fine-meshed drum sieve for a silky, light texture. You can prepare the purée in advance up to this stage and store it in the fridge. To serve, reheat it gently in a pan, while gradually whisking in a little warm milk.
