Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Orange 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the egg yolks and sugar until light.
Add the orange juice, grated rind, and cold water; mix well.
In another bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture.
In a separate bowl, beat the egg whites until stiff peaks form; fold into the batter.
Pour the batter into a greased cake pan.
Bake and finish
Bake for 25-30 minutes or until a toothpick comes out clean.
Let cool and frost with orange icing.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Yolks enrich and bind the batter, while whipped whites add lift and airy structure.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- Sugar
- Sweetens the cake and helps beaten eggs hold a light, aerated texture.
- Flour
- Forms the cake's structure once the batter sets in the oven.
- Orange
- Adds juice for moisture and flavor, and grated rind adds aroma.
The step that matters
Folding in the egg whites. Egg whites hold air only when beaten to stiff peaks, and overmixing when folding deflates them. Gentle folding keeps the air that gives the cake its rise and light crumb.

Fit is the average pairing score against egg, sugar, flour, butter, milk, vanilla. Candidates are from the same food group and used in at least 100 recipes.
