Why it works: Beans and vanilla match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,293 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Walnut Cake
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 batter
Preheat the oven to 350°F (175°C).
Beat the egg yolks lightly with the sugar.
Add the ground coffee, vanilla, lemon juice, and grated nuts, mixing well.
Beat the egg whites until stiff peaks form. Gently fold the beaten egg whites into the yolk mixture.
Bake and fill
Divide the batter into two layers and bake for 25-30 minutes.
Beat the filling egg yolks with sugar, cream, and cornstarch until smooth. Cook the mixture in a double boiler until thick, then cool.
Add vanilla and the reserved nuts to the filling. Spread the filling between the baked layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Enrich the batter and add richness and colour to the cake.
- Egg whites
- Whipped to stiff peaks, they give the batter lift and an airy structure.
- Granulated sugar
- Sweetens the batter and helps stabilise the beaten yolks.
- Grated nuts
- Provide the main body, flavour and tender crumb of the cake.
- Cornstarch
- Thickens the cooked filling so it sets smooth and spreadable.
The step that matters
Gently fold the beaten egg whites into the yolk mixture. Whipped egg whites trap air that gives the cake its rise. Stirring or deflating them vigorously knocks out that air, leaving a dense layer.

Fit is the average pairing score against egg, sugar, coffee, beans, vanilla, nuts, cream. Candidates are from the same food group and used in at least 100 recipes.
