Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Orange Cake
Ingredients
Directions
The book says “a medium oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the batter
Sift the sugar and flour three times separately.
Mix the sifted sugar and flour together.
Stir in the well-beaten egg whites.
Add cream of tartar with the sugar and flour before adding the eggs.
In a separate bowl, cream the sugar and butter until smooth.
Add the egg yolks, milk, and lemon juice, and mix well.
Sift in the flour with baking powder and mix until smooth.
Fold in the beaten egg whites gently.
Bake
Divide the batter into four layers.
Bake in a moderate oven (350°F / 175°C).
Fill and frost
Once cooled, chop the oranges finely and sweeten them to taste.
Spread the chopped oranges over three of the layers.
Prepare a soft-boiled frosting with egg whites, sweeten it to taste, and add grated lemon peel.
Stack the layers and add frosting between 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.

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
- Trapped air in the beaten whites lifts the batter and gives the cake its light structure.
- All-purpose flour
- Its proteins set during baking to form the cake's main structure.
- Baking powder
- Releases gas when heated, causing the batter to rise in the oven.
- Butter
- Fat coats flour particles and tenderizes the crumb, adding richness.
- Granulated sugar
- Adds sweetness and helps keep the crumb tender and moist.
- Milk
- Adds moisture that hydrates the flour and gives a softer crumb.
The step that matters
Fold in the beaten egg whites gently. The whites hold air bubbles that lift the batter as it bakes. Overmixing deflates that foam, leaving a denser cake.
Swap the orange
How well each one fits the dish's main ingredients (sugar, butter, egg, milk, lemon, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against sugar, butter, egg, milk, lemon, flour. Candidates are from the same food group and used in at least 100 recipes.
