Why it works: Flour and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Orange Cream 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.
Make the cake
Preheat the oven to 350°F (175°C).
In a bowl, mix flour and baking powder.
In another bowl, beat egg yolks and sugar until creamy.
Add water, orange juice, and grated orange rind to the yolk mixture.
Gradually add the flour mixture to the wet ingredients.
In a separate bowl, beat egg whites until stiff peaks form.
Fold the beaten egg whites into the batter gently.
Pour the batter into a greased cake pan and bake for 30-35 minutes.
Make the filling and finish
For the filling, beat 1 egg white to stiff froth, then gradually add powdered sugar until stiff.
Mix in the juice and grated rind of 1 orange.
Once the cake is cool, spread the orange cream filling on top.

Flour and egg 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
- Flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Egg yolks
- Add richness and moisture, and help bind the batter.
- Egg whites
- Whipped to stiff peaks, they trap air that lightens the batter and helps it rise.
- Baking powder
- Releases gas during baking, causing the cake to rise and become light.
- Sugar
- Sweetens the cake and helps keep it tender and moist.
- Orange juice
- Adds moisture and bright citrus acidity and flavour to the batter.
The step that matters
Fold the beaten egg whites into the batter gently. Stiff whipped whites hold air that makes the cake light. Vigorous stirring knocks that air out, so the cake bakes up dense instead of airy.
Swap the orange
How well each one fits the dish's main ingredients (flour, sugar, egg):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
