Separate the egg yolks and place them in a saucepan with the sugar, then add the coffee and the coffee liquor. Mix with a whisk and start to whip the eggnog in a bain-marie until the mixture appears soft and the volume is doubled.

Then cut the slices of panettone and grill slightly on both sides.

Place a slice of panettone next to the eggnog ice cream and decorate the plate with berries. To finish it off, sprinkle the entire plate with powdered sugar.
