Biscuit Glaces

Ingredients

Directions

Make the custard

  1. Heat half of the cream until it boils.

  2. Beat the egg yolks and sugar until very light.

  3. Remove the boiling cream from heat and stir in the egg and sugar mixture while still hot.

  4. Let the mixture cool, then add the Maraschino or Kirsch and freeze like ice cream.

  5. Whip the remaining cream to a thick froth, adding the vanilla, and stir it into the freezing cream.

Mold and freeze

  1. Prepare paper cases or molds for Biscuit Glaces and fill them with the mixture.

  2. Top with a little of the whipped cream colored with 1 teaspoon of strawberry extract and a few drops of cochineal.

  3. Pack the molds in salt and freeze for two more hours until they can be turned out whole.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Cooked into the hot cream, they thicken the mixture and give it a rich, smooth body.
Cream
Provides fat and moisture, giving the frozen glace a smooth, creamy texture.
Sugar
Sweetens the mixture and lowers the freezing point, keeping the glace soft rather than rock hard.
Vanilla extract
Adds aroma and flavor to the whipped cream folded into the mixture.

The step that matters

Stirring the egg and sugar into the hot cream. If the cream is not hot enough or is added too quickly, the yolks can scramble instead of thickening smoothly. Stirring steadily while the cream is hot gently cooks the yolks into a smooth custard base.
