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 ↓
One-egg 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
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, mix melted butter and sugar until well combined.
Add the egg yolk and milk, and stir until smooth.
In another bowl, combine flour, baking powder, salt, and ground chocolate.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Gently fold in the beaten egg white.
Bake
Pour the batter into a greased cake 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 white
- Whipped to stiff peaks, it traps air that lifts the cake as it bakes.
- Flour
- Forms the structure that holds the cake's crumb once baked.
- Baking powder
- Releases gas during baking, helping the cake rise and become light.
- Egg yolk
- Adds richness and helps bind the batter while contributing to tenderness.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps give it a soft, tender texture.
The step that matters
Folding in the egg white. Stiffly beaten egg white holds air that makes the cake light. Stirring vigorously or overmixing deflates it, leaving a dense cake, so fold gently until just combined.
“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.
