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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the sweet milk and beaten eggs, mixing well.
In a separate bowl, combine the baking powder and flour, then mix into the wet ingredients.
Bake and fill
Divide the batter into four layers and bake until golden.
For the filling, combine the grated orange rind, orange juice, sugar, egg, and coconut in a saucepan.
Boil the mixture for about 2 minutes, then spread between the cake layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Butter
- Adds richness and tenderness to the crumb.
- Baking powder
- Releases gas in the batter so the layers rise light.
- Flour
- Forms the main structure that holds the cake layers together.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
- Orange juice
- Adds acidity and bright citrus flavour to the cake and filling.
The step that matters
Boil the filling for about 2 minutes. The egg in the filling must be heated enough to thicken the mixture; stirring constantly over heat keeps it smooth and prevents it from scrambling or sticking to the pan.
Swap the coconut
The recipe marks coconut as optional. How well each one fits the dish's main ingredients (sugar, butter, milk, egg, flour, orange):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Coconutthe original
Fit is the average pairing score against sugar, butter, milk, egg, flour, orange. 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.
