Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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).
Cream the butter and 2 cups of sugar together.
Add the yolks of 5 eggs and the beaten whites of 5 eggs to the mixture.
Stir in the flour, baking powder, and whiskey.
Bake in layers until golden.
Make the filling
For the filling, combine the juice of 4 oranges, 1 tablespoon butter, yolks of 2 eggs, 1 ½ cups sugar, and 1 tablespoon flour in a saucepan.
Cook until thick, then spread between the layers of cake.
Make the icing
For the icing, mix the juice of the remaining 2 oranges with sugar and the whipped whites of 2 eggs.
Cook until thick and pour over the top of the cake.

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.

Flour and butter 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
- Eggs
- Yolks and whites add richness, structure and lift to the cake and set the filling and icing.
- Flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Butter
- Adds fat for a tender crumb and rich flavour in the cake and filling.
- Sugar
- Sweetens the cake, filling and icing and helps keep the crumb moist and tender.
- Oranges
- Supply the juice that flavours the cake, filling and icing with acidity and aroma.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
The step that matters
Cooking the filling until thick. Egg yolks thicken as they heat and set the custard, but overheating can curdle them. Cook gently and stir constantly so the filling thickens smoothly before spreading.
Swap the orange
How well each one fits the dish's main ingredients (egg, flour, butter, milk, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against egg, flour, butter, milk, sugar. 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.
