KachkÊis Fondue with Mustard Croutons - Luxembourg traditional dish

🧂 Ingredients

  • 1.5 medium Baguette(cut into bite-sized pieces)
  • 4.5 tbsp Wholegrain mustard
  • 4.5 tbsp Smooth mustard
  • 3 tbsp Water(for croutons)
  • 500 g KachkÊis log(uncooked, cut into pieces)
  • 200 ml White wine
  • 50 ml Cream
  • 2 large Garlic cloves(peeled and crushed)
  • 300 g Gruyère cheese(grated)
  • 3 tbsp Cornflour
  • 70 ml Kirsch
  • 1 tsp Salt(for croutons)
  • 1 tsp Black pepper(freshly ground)

đŸ‘¨â€đŸŗ Instructions

  1. 1

    Preheat oven to 180°C fan (350°F). Place baguette pieces on a baking tray.

  2. 2

    In a small bowl, mix the wholegrain and smooth mustards with water until smooth. Pour over the baguette pieces and toss to coat evenly. Sprinkle with salt.

  3. 3

    Bake the croutons for 15 minutes until crispy, turning halfway through. Set aside.

  4. 4

    In a fondue saucepan (caquelon), combine the KachkÊis pieces, white wine, and cream. Heat gently until the cheese is melted and smooth.

  5. 5

    Add the crushed garlic and grated Gruyère cheese to the melted KachkÊis. Stir until well combined and smooth. Season with pepper.

  6. 6

    In a small jar, whisk together the cornflour and Kirsch until smooth. Stir this mixture into the fondue to thicken. Cook for a couple of minutes, stirring constantly.

  7. 7

    Serve the hot KachkÊis fondue immediately with the mustard croutons, gherkins, and a green salad.

💡 Pro Tips

  • ✓KachkÊis can be found in some specialty European delis or online.
  • ✓If Kirsch is unavailable, a splash of brandy or even water can be used, though Kirsch adds a traditional flavor.
  • ✓Clean the fondue pot immediately after use to prevent cheese from hardening.

🔄 Variations

  • Add a pinch of nutmeg to the fondue for extra warmth.
  • Serve with crusty bread or boiled potatoes instead of croutons.
  • For a less alcoholic version, omit the Kirsch or replace with a little more water.
