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 cake
Preheat the oven to 350°F (175°C).
In a bowl, combine the sifted flour and baking powder.
Beat the 5 eggs. Add 2 cups of sugar, 1 cup of butter, and 1 cup of milk.
Gradually mix the dry ingredients into the wet mixture until well combined.
Pour the batter into thin layers on baking sheets.
Bake until golden.
Make the custard
For the custard, combine the orange juice, grated rind, and reserved egg yolks in a saucepan.
Sweeten to taste.
Stir over low heat until thick enough to spread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs bind the batter and give the cake structure as they set.
- Flour
- Forms the structure of the cake as its starches set during baking.
- Baking powder
- Releases gas in the batter so the thin layers rise and turn light.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps it brown while baking.
- Egg yolks
- Thicken the orange custard as they cook gently over low heat.
The step that matters
Stirring the custard over low heat. Egg yolks thicken as their proteins set, but high heat can scramble them. Gentle, constant stirring keeps the custard smooth and thick enough to spread.
Swap the orange
How well each one fits the dish's main ingredients (flour, egg, sugar, butter, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against flour, egg, sugar, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
