Ingredients for Make-ahead mashed potatoes

  • 1,800–2,000 g medium yukon gold potatoes, scrubbed

  • kosher salt

  • 160–240 ml double cream

  • 160–240 ml full-fat milk

  • 280 g unsalted butter, cut into pieces

  • 120 ml soured cream

  • freshly ground black pepper

  • a potato ricer or food mill fitted with fine disk

How to make Make-ahead mashed potatoes

  1. Place the potatoes in a large pot and cover them with cold water by about 2.5 cm. Add a large handful of salt (the water should taste briny, like the sea) and bring to the boil. Reduce the heat and simmer for 30–40 minutes, or until the potatoes are very tender but not crumbly. Drain the potatoes and return them to the warm pot to dry (off the heat).

  2. Meanwhile, heat 160 ml of single cream and 160 ml of milk in a small saucepan over medium heat until just about to simmer. Reduce the heat to low and keep warm until ready to add to the potatoes.

  3. Pass the hot potatoes and butter through a ricer into a large bowl (this helps combine them quickly; most of the skins should remain behind, but remove any small pieces that get through if desired). Season generously with salt.

  4. Use a potato masher to mix the potatoes until the butter is melted and evenly combined.

  5. While mixing constantly, gradually add the warm cream mixture to the potatoes, then stir in the sour cream. Taste and season with salt and pepper as desired.

  6. The mashed potatoes can be prepared up to 2 days in advance. Allow to cool, then cover and chill in the fridge.

  7. To serve, transfer the potatoes to a small pot and add 80 ml of double cream and 80 ml of whole milk. Reheat over medium-low heat, stirring often to prevent scorching.
