Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. 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 cake
Preheat the oven to 350°F (175°C).
Beat the yolks of 5 eggs well.
Mix in 2 cups of sugar, ½ cup of cold water, the juice and rind of 1 orange, 1 teaspoon of baking soda, and 2 teaspoons of cream of tartar.
Gradually add 2 cups of flour to the mixture.
In a separate bowl, beat the whites of 3 eggs to a stiff froth and fold them into the batter.
Pour the batter into two cake pans and bake until golden.
Make the frosting and assemble
For the frosting, combine 2 egg whites with 3 cups of powdered sugar and the juice and rind of 2 oranges without beating the whites.
Once the cake is cooled, split it and spread frosting between the layers and on top.

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.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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 yolks
- Enrich the batter with fat and emulsifiers, giving a tender, rich crumb.
- Egg whites
- Whipped to a stiff froth, they trap air that lifts and lightens the cake.
- Flour
- Forms the gluten and starch structure that sets the cake's crumb.
- Sugar
- Sweetens the cake and helps keep it moist and tender.
- Baking soda
- Reacts with the acid in the batter to release gas, helping the cake rise.
- Cream of tartar
- Acidic partner to the baking soda that helps it react and stabilizes the batter.
The step that matters
Folding in the beaten egg whites. Stiff egg whites hold the air that lifts the cake. Folding gently keeps that air in; stirring hard deflates the batter and yields a dense cake.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, cream, flour):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
