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 Part
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).
In a bowl, cream together the sugar and butter until light and fluffy.
Add the milk and mix well.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the sugar mixture.
Sift together the flour and baking powder, then fold into the mixture.
Add the strawberry flavoring and mix until just combined.
Bake
Pour the batter into a greased baking pan and bake for 25-30 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 whites
- Whipped to stiff peaks, they trap air that lightens and raises the cake's crumb.
- Butter
- Creamed with sugar, it adds fat that gives the cake tenderness and a rich texture.
- Flour
- Forms the cake's structure as its proteins set during baking.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- White sugar
- Sweetens the cake and, creamed with butter, helps hold air for a light texture.
The step that matters
Folding in the egg whites. Whipped egg whites hold air that gives the cake its lift. Stirring them in roughly or overmixing knocks that air out, so the cake bakes up dense. Fold gently until just combined.
Swap the strawberry
How well each one fits the dish's main ingredients (sugar, butter, milk, egg, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Strawberrythe original
Fit is the average pairing score against sugar, butter, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
