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 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
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together.
Add part of the milk to the butter and sugar mixture.
Sift the flour and baking powder together.
Add the sifted mixture to the batter alternately with the remaining milk.
Fold in the beaten egg whites gently to retain air.
Pour the batter into a greased cake pan and bake until golden.
Make the filling
For the filling, combine ½ cup sugar, 2½ tablespoons flour, lemon juice, grated orange rind, and beaten egg in a double boiler.
Cook the filling for about 10 minutes, stirring constantly.
Make the frosting
For the frosting, mix the grated orange rind, brandy, lemon juice, and orange juice.
Stir in enough confectioner's sugar to achieve a spreadable consistency.
If too thick, thin with a little orange juice before spreading.

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
- Flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Eggs
- Add structure and richness, and set as the cake bakes.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps keep it moist and tender.
- Milk
- Adds moisture so the batter mixes to a smooth, pourable consistency.
The step that matters
Cook the filling gently while stirring constantly. The egg in the filling thickens as its proteins set with heat. Stirring keeps the heat even and prevents the egg from scrambling or curdling in the double boiler.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, milk, flour, egg, lemon, brandy):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, sugar, milk, flour, egg, lemon, brandy. Candidates are from the same food group and used in at least 100 recipes.
