Ingredients

Directions

Make the custard

  1. Stir the egg yolks and sugar in a bowl until they bubble, but do not beat.

  2. Boil the milk in a bain-marie.

  3. Stir the egg and sugar mixture into the boiling milk.

  4. Simmer the mixture to thicken without boiling.

  5. Strain the custard through Swiss muslin.

  6. Let the custard cool.

  7. If using a vanilla bean, boil it in the milk.

  8. If using vanilla extract, stir it into the custard when cold.

Prepare the cream

  1. Pack the sweet cream in ice and salt until very cold.

  2. Whip the cold cream until thick.

Freeze and pack

  1. Fold the whipped cream into the cold custard gradually.

  2. Freeze the mixture until stiff.

  3. Optionally, add quartered crystallized fruit after the cream is partially frozen.

  4. Stir the fruit into the mixture before packing.

  5. Pack the mixture into molds and ice.

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

What each ingredient does

Egg yolks
Thicken the custard as they set gently with heat, giving it richness and a smooth body.
Sugar
Sweetens the custard and lowers the freezing point, keeping the ice cream softer.
Sweet milk
Forms the liquid base of the custard that the yolks thicken.
Double sweet cream
Whipped into the custard, adding fat and air for a light, creamy texture.
Vanilla
Adds the characteristic aroma and flavour to the custard.

The step that matters

Simmer the custard without boiling. Egg yolks thicken gently as they warm, but if the custard boils they can curdle and turn grainy. Keeping it just below boiling lets it thicken smoothly.
