Why it works: Almond and flour are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Ratafias
Ingredients
Directions
Make the almond paste
Blanch and dry the almonds in the sun, then pound them with sifted sugar until well combined.
Add egg whites one at a time to form a thin paste.
Drop walnut-sized pieces onto wafer paper, sprinkle with sliced almonds and sugar, and bake in a slow oven until light brown.
Make the sponge
Beat the yolks of 12 eggs and the whites of 6 eggs separately.
Combine the yolks with sugar and beat until light.
Gradually stir in flour, then fold in beaten egg whites.
Add chopped almonds and pour into a pan, baking for 1.5 hours.
Shape and bake the cakes
Mix Ratafia cakes, almonds, sugar, and lime rind, then combine with egg whites to form small balls.
Place on paper and bake in a moderate oven.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites and yolks give the cake its light, airy structure as they set in the oven.
- Sweet almonds
- Ground almonds add body, moisture and a rich nutty flavour to the cakes.
- Sugar
- Sweetens the cakes and helps the yolks and whites beat to a stable, light texture.
- Flour
- Provides structure so the folded batter sets into a cake rather than collapsing.
- Butter
- Adds fat for richness, tenderness and a softer crumb.
The step that matters
Folding in the beaten egg whites. Whites hold air only when beaten properly and folded in gently; overmixing or deflating them makes the cake dense and flat instead of light.
Swap the lime
How well each one fits the dish's main ingredients (almond, sugar, egg, flour, butter):

- Vanillafits better
- Figfits better
- Limethe original
Fit is the average pairing score against almond, sugar, egg, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
