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 sugar together until light and fluffy.
Beat the eggs for 10 minutes, then add to the butter mixture.
Stir in the sweet milk.
Sift together the flour and baking powder, then gradually add to the mixture.
Pour the batter into a greased cake pan and bake until golden.
Make the icing and finish
For the icing, cook 2 cups of sugar with enough water until it drops like candy.
Pour the hot icing over the well-beaten egg whites and mix until smooth.
Once the icing cools, decorate the cake with slices of oranges.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cake a light, tender crumb and rich flavor.
- Eggs
- Add structure and richness, and their beaten foam helps the cake rise and set.
- Flour
- Forms the cake's structure once mixed with the liquid and set by baking.
- Baking powder
- Releases gas in the batter so the cake rises and becomes airy.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Egg whites
- Whipped into the hot icing to create a light, fluffy, marshmallow-like topping.
The step that matters
Pouring the hot icing over the egg whites. The sugar syrup must be hot enough to cook the egg whites as it is poured while mixing constantly. Pouring too slowly or without beating can leave lumps or a runny, uneven icing.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, sugar, egg, milk, 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.
