Why it works: Vanilla and nuts work together. They rank in the top 8% of all ingredient pairs, and cooks put them together in 638 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓

Ingredients
Directions
Make the syrups
In a saucepan, combine 2 cups of sugar and ½ cup of water. Cook until it reaches the 'hair' stage.
In another saucepan, combine 1 cup of sugar, ½ cup of water, and 2 tablespoons of glucose. Cook until it reaches the 'hair' stage.
Beat and flavor
Pour the first mixture over the stiffly beaten egg whites, beating constantly.
Once the second mixture is ready, pour it over the egg whites while continuing to beat.
Flavor with vanilla. When it begins to cream, add chopped nuts or fruits if desired.
Fill and ice
Spread between cakes and ice the top with plain white icing. Nuts and fruits can be omitted if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Granulated sugar
- Forms the syrup that sets into the icing's sweet, soft structure.
- Egg whites
- Whipped into foam that gives the icing its light, airy texture.
- Glucose or corn syrup
- Interferes with sugar crystallization, keeping the icing smooth rather than grainy.
The step that matters
Beating the syrup into the egg whites. Hot syrup must be poured slowly while beating constantly so it cooks the whites into a stable foam without deflating them or forming lumps. Beating is needed until the icing begins to cream and loses its gloss.
Swap the nuts
The recipe marks nuts as optional. How well each one fits the dish's main ingredients (sugar, corn, egg, vanilla):
- Almondfits better
- Chestnutfits better
- Hazelnutfits better
- Nutsthe original
Fit is the average pairing score against sugar, corn, egg, vanilla. Candidates are from the same food group and used in at least 100 recipes.
