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 Loaf Cakes
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, beat the egg yolks and butter until creamy.
Add the sugar and mix well.
Sift together the flour and baking powder, then add to the mixture.
Squeeze the juice from the orange into a cup and add sweet milk until the cup is full.
Mix the orange juice and milk into the batter until well combined.
Bake
Pour the batter into a greased loaf pan and bake for about 45 minutes or until a toothpick comes out clean.

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
- Egg yolks
- Add richness and structure, helping the batter set into a tender crumb when baked.
- Butter
- Adds fat for a tender texture and rich flavor in the crumb.
- Sugar
- Sweetens the cake and helps keep it moist and tender while it bakes.
- Flour
- Provides the main structure that sets the crumb as the cake bakes.
- Baking powder
- Releases gas during baking so the loaf rises and becomes light.
- Orange juice
- Adds moisture and bright citrus acidity and aroma to the batter.
The step that matters
Mix the orange juice and milk into the batter until well combined. Mixing in the liquid evenly keeps the batter emulsified and the rise uniform. Once the flour is in, overmixing develops gluten and can make the loaf tough and dense.
Swap the orange
How well each one fits the dish's main ingredients (egg, butter, sugar, flour, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against egg, butter, sugar, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
