Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. 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.
Make the batter
Beat the egg whites and yolks separately.
Cream the sugar and butter together.
Add the beaten eggs and cold water to the mixture.
Sift in the flour and baking powder, then mix well.
Stir in the juice and grated rind of the orange.
Bake
Pour the batter into a greased baking pan.
Bake at 350°F (175°C) until golden brown.

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.

Butter and flour 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
- Egg whites
- Whipped separately to trap air, giving the cake lift and a light crumb.
- Egg yolks
- Add richness and fat, and help bind the batter to a tender texture.
- Butter
- Creamed with sugar to add fat, softness and a tender crumb.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
The step that matters
Beating the egg whites separately. Whites must be beaten until they hold air, because that trapped air is what lifts the batter. Under-beaten or greasy whites give a dense cake.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, butter, flour):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
