Why it works: Chocolate and coffee are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,497 recipes. Both carry 2,3-butanedione, which smells buttery, creamy. The science ↓
Meringues
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the meringues
Beat the egg whites to stiff peaks.
Gradually mix in the caster sugar.
Add vanilla extract and mix well.
Spoon the mixture onto a baking sheet in egg-shaped portions.
Sift a little caster sugar over the meringues and shake off excess.
Bake in a 400°F (200°C) oven until golden.
Fill and serve
Remove from paper and hollow out the centers carefully.
Boil the coffee with caster sugar until it forms a syrup.
Let the syrup cool, then mix in whipped double cream.
Fill the hollowed meringues with the coffee cream and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a foam that holds air, giving the meringues their structure and light texture.
- Caster sugar
- Stabilises the whipped whites and sweetens the meringues, helping them turn crisp and golden.
- Double cream
- Adds fat and richness, giving the coffee filling a smooth, soft texture.
- Strong coffee
- Provides the main flavour of the filling, with its sugar syrup adding sweetness.
The step that matters
Beat the egg whites to stiff peaks. Egg whites must be whipped until they hold firm peaks so they trap air. Underwhipped whites stay runny and bake flat, while overwhipped whites turn grainy and collapse.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
