Why it works: Vanilla and almond match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,961 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Gateau Mocha and Coffee Cream
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the cake
Preheat the oven to 350°F (175°C).
In a bowl, stir together the sugar and egg yolks.
Whip the egg whites until stiff peaks form, then gently fold them into the yolk mixture.
Add the flour, vanilla extract, and rum, and mix until combined.
Pour the batter into a buttered and papered cake hoop and bake until done.
Once baked, turn the cake upside down on a sieve and let it cool overnight.
Cut the cooled cake into three horizontal slices.
Make the mocha cream
Prepare the coffee essence by boiling the coffee in water for 30 minutes; bottle any leftover for future use.
For the mocha cream, slightly warm the butter and mix in the icing sugar and coffee essence gradually until smooth.
Assemble and decorate
Spread the mocha cream between the cake layers and cover the entire cake with a thin layer of cream.
Smooth the surface with a knife, then brown and chop the almonds.
Press the chopped almonds onto the sides of the cake.
Use a star piping tip to pipe a design on top of the cake with the remaining cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they trap air that gives the cake its light, airy structure.
- Egg yolks
- Add richness and fat, and help bind the batter for a tender crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Adds fat and richness to the mocha cream, giving it a smooth, spreadable texture.
- Sugar
- Sweetens the cake and helps create a tender crumb and golden browning.
- Coffee
- Provides the coffee flavour that defines the mocha cream.
The step that matters
Folding the whipped egg whites into the yolk mixture. Overmixing or deflating the whipped whites releases the air that lifts the batter, leaving a dense, flat cake. Fold gently, just until no white streaks remain.
