Parfaits and Spong-adas

Ingredients

Directions

Make the custard

  1. In a pan over hot water, whisk the egg yolks and sugar until warm and thick.

  2. Remove from heat and stir in the hot coffee, continuing to beat until cold and creamy.

  3. Once cold and light, quickly fold in the whipped cream.

Freeze

  1. Pour the mixture into a mold and freeze for about 3 hours.

  2. If using ice and salt, weigh down the lid to keep it closed properly.

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

What each ingredient does

Eggs
Yolks thicken as they warm and whisk, forming the rich custard base.
Caster sugar
Adds sweetness and helps the yolks whisk to a thick, stable foam.
Coffee
Provides the main liquid and coffee flavour, chilled into the custard.
Whipped cream
Adds lightness and a smooth, creamy texture to the frozen dessert.

The step that matters

Warm the yolks gently over hot water. Egg yolks scramble if they get too hot too fast. Gentle, steady heat while whisking thickens them smoothly into a custard that holds air and sets well when frozen.
