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 ↓
White Loaf Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; 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
Cream the butter and sugar together until light and fluffy.
Add the milk and mix well.
Gradually add the flour and baking powder, mixing until combined.
Fold in the beaten egg whites, salt, and lemon extract.
Bake
Pour the batter into a greased loaf pan.
Bake for 30-35 minutes or until a toothpick inserted in the center 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
- Butter
- Creaming with sugar traps air, giving the cake a light, tender crumb and rich flavour.
- Sugar
- Sweetens the cake and helps hold air when creamed with butter, supporting a light texture.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter so the loaf rises and becomes airy.
- Egg whites
- Folded in beaten, they add lift and structure to the crumb.
The step that matters
Folding in the beaten egg whites. Folding gently keeps the air whipped into the egg whites. Stirring vigorously knocks out that air, so the loaf rises less and turns denser.
Swap the lemon
How well each one fits the dish's main ingredients (butter, sugar, milk, flour, egg):

Fit is the average pairing score against butter, sugar, milk, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
