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 ↓
Delicate 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).
In a large bowl, beat the egg whites until stiff peaks form.
In another bowl, cream the butter and sugar together until light and fluffy.
Add the sweet milk and mix well.
Gradually add the flour, corn starch, cream of tartar, and soda, mixing until smooth.
Fold in the beaten egg whites gently.
Bake and serve
Pour the batter into prepared pans.
Decorate the top with thin pieces of preserved citron peel before baking.
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
- Beaten to stiff peaks, they trap air that lifts the cake and gives it a light, delicate crumb.
- Butter
- Creamed with sugar to trap air and add richness and a tender texture.
- Sugar
- Creamed with butter to help build a light, fluffy base and add sweetness.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Cream of tartar
- Stabilizes the whipped egg whites and adds acidity that helps the cake rise evenly.
- Soda
- Reacts with the acidity in the batter to produce gas that makes the cake rise.
The step that matters
Folding in the beaten egg whites. Folding gently keeps the air bubbles in the whipped whites intact. Stirring vigorously knocks out the air, which leads to a dense, flat cake instead of a light one.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
