Equipment

  • 1 potato ricer
  • 1 sieve

Ingredients
  

  • 2 lbs Yukon Gold potatoes peeled and cubed
  • salt for boiling the water
  • 1 cup heavy cream
  • 1 garlic clove
  • 1 tbsp Boursin garlic & fine herbs, green package
  • 1 tbsp crème fraîche I get mine at Trader Joe's
  • 3-4 cups cheese (see note) (1/2 Gruyère and 1/2 mozzarella or tomme; substitute with a mix of melty cheeses if needed)
  • 4 tbsp butter cubed
  • chopped chives for garnish

Instructions
 

  • In a large pot, add the cubed Yukon Gold potatoes and enough salted water to cover them. Boil until fork-tender, about 20–30 minutes.
  • While the potatoes cook, warm the heavy cream in a small saucepan with the crushed garlic clove and the tablespoon of Boursin. Let it infuse gently without boiling. Remove garlic once infused.
  • Drain the potatoes and work quickly while they’re still hot. Using a potato ricer and later a sieve, work them until completely smooth. Stir in the tablespoon of crème fraîche.
  • Begin adding the warm cream gradually while stirring. Add a handful of cheese, then mix until melted. Repeat this process (cream, mix, cheese, mix) until the potatoes turn silky and stretchy.
  • Stir in cubed butter until fully melted and incorporated.
  • The aligot should have a smooth, elastic texture. Serve immediately, topped with chopped chives.

Notes

  • Traditional aligot uses Tomme de Laguiole or Cantal cheese. If you can’t find them, use a combination of Gruyère and mozzarella for melt and stretch.
  • Avoid adding extra salt or pepper because the butter and cheese already provide plenty of seasoning.
  • Aligot is best served hot and freshly made.
