Why it works: Coffee and sugar are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 4,344 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Coffee Sponge
Ingredients
Directions
Make the coffee jelly
Soak gelatine in cold water for 5 minutes.
Dissolve gelatine in boiling coffee and add sugar, stirring until dissolved.
Strain the mixture and set it in ice water.
When it begins to thicken, beat the egg whites to a stiff froth.
Whip the jelly into the egg whites, a spoonful at a time, using an egg beater.
Set and serve
Pour the mixture into a mold and place it on ice to harden.
Serve with cream.

What each ingredient does
- Gelatine
- Sets the coffee liquid into a jelly that holds the whipped foam.
- Egg whites
- Whipped to a stiff froth, they give the dessert its light, airy texture.
- Sugar
- Adds sweetness and balances the bitterness of the coffee.
- Black coffee
- Provides the main flavour and liquid base of the sponge.
The step that matters
Whip the jelly into the egg whites a spoonful at a time. Adding the thickening jelly slowly lets it blend evenly into the foam, so the air bubbles are not collapsed and the sponge stays light.
