Ingredients Method Notes

Ingredients
  

  • 8 oz 225g Fontina cheese (preferably Italian Fontina Val d’Aosta)
  • 1 cup whole milk
  • 2 tbsp unsalted butter
  • 2 large egg yolks
  • Salt to taste
  • Freshly ground black pepper to taste
  • Optional Thin white truffle shavings or white truffle purée (for garnish)

Method
 

Prepare Cheese:
  1. Slice the Fontina cheese into thin, even slices. Soak the slices in the whole milk for at least 1 hour in the fridge (you can leave it up to 3 hours or overnight for better results).
Set up Double Boiler:
  1. Bring a small saucepan of water to a simmer. Place a heatproof bowl over the saucepan without letting it touch the water (or use a double boiler if available).
Melt the Cheese:
  1. Drain the cheese from the milk and reserve the milk for later use. Place the drained cheese into the heatproof bowl. Whisk gently as it starts to melt; the texture may initially appear clumpy, but keep whisking steadily.
Add Butter:
  1. Once the cheese begins to melt, add the butter in small pieces, whisking continuously until the sauce becomes glossy.
Add Egg Yolks:
  1. Off the heat, whisk in the egg yolks one at a time. Fully incorporate each yolk before adding the next to avoid scrambling.
Adjust with Milk:
  1. Gradually add the reserved milk (a little at a time), whisking continuously until the sauce reaches a pourable, spoonable consistency. You may not need all the milk.
Season and Finish:
  1. Season the fonduta with a pinch of salt and freshly ground black pepper. Optionally, add a small amount of truffle purée or thin shavings of white truffle off the heat.
Serve:
  1. Serve the fonduta hot with bread cubes, boiled potatoes, steamed vegetables, or polenta. Keep the fonduta warm over a low flame or gently reheated.

Notes

  • The milk soak helps the cheese melt smoothly and prevents clumping. Don’t skip this step!
  • You can substitute Fontina with other alpine cheeses like Taleggio or Emmental if Fontina is unavailable, but it might slightly alter the flavor.
  • The key to this dish is gentle heat and patience while whisking to prevent the egg yolks from scrambling.
