Why it works: Sugar and flour 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 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 and fluffy.
Add the orange juice, grated rind, and cold water; mix well.
In another bowl, sift together the flour and baking powder.
Gradually add the dry ingredients to the wet mixture, stirring until combined.
Fold and bake
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
Pour the batter into a greased cake pan and bake for 30-35 minutes or until a toothpick comes out clean.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
- Add richness and tenderness, and help bind the batter together.
- Egg whites
- Whipped to stiff peaks, they add lift and an airy crumb to the cake.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas as it reacts in the batter, helping the cake rise.
- Sugar
- Sweetens the cake and helps the beaten yolks become light and fluffy.
- Orange
- Adds bright citrus flavour and aroma from the juice and zest.
The step that matters
Folding in the egg whites. Whisked whites hold air that gives the cake its lift. Stirring them in vigorously knocks out that air, so the cake comes out dense. Fold gently with a spatula until just combined.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, flour):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, 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.
