Coffee Gelatine

Ingredients

Directions

Make the custard

  1. Dissolve the gelatine in a little cold water.

  2. Add boiling coffee, then beat together the yolks of the eggs, milk, and sugar.

  3. Combine this mixture with the gelatine and cook in a double boiler until it thickens slightly.

  4. Remove from heat and fold in the stiffly beaten egg whites until just mixed.

  5. Stir in the vanilla.

Set and serve

  1. Pour into a mold to harden.

  2. Serve sliced with a sauce made of thick cream, slightly sweetened and flavored with vanilla.

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

What each ingredient does

Gelatine
Sets the liquid into a firm, sliceable dessert as it cools.
Eggs
Yolks thicken the custard while whites are folded in to lighten the texture.
Milk
Adds richness and softness to the custard base.
Sugar
Sweetens the dessert and balances the bitterness of the coffee.
Boiling coffee
Provides the main flavour of the dessert.

The step that matters

Combine the custard with the gelatine and cook gently in a double boiler. Egg yolks can curdle or scramble if overheated, so gentle indirect heat is needed until the mixture only thickens slightly. Gelatine must also be fully dissolved and evenly mixed for the dessert to set smoothly.
