Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Loaf 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. 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 the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the egg yolks and mix well.
Stir in the milk and vanilla.
In a separate bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture.
In another bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
Bake
Pour the batter into a greased loaf pan.
Bake for 30-40 minutes or until a toothpick inserted in the center comes out clean.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Eggs
- Yolks enrich and bind the batter, while whipped whites add lift and a light texture.
- Butter
- Creamed with sugar, it traps air and adds richness and a tender crumb.
- Sugar
- Creamed with butter, it helps build a light, fluffy structure and adds sweetness.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas in the oven, helping the loaf rise.
The step that matters
Folding in the egg whites. Whipped whites trap air that gives the loaf its lift. Stirring them vigorously knocks out that air and leaves a dense cake, so fold gently with a spatula until just combined.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, milk, egg, flour, butter):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against sugar, milk, egg, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
