Why it works: Milk and butter 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 ↓

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.
Make the dough
In a bowl, mix the egg yolks, warm milk, yeast, and butter to form a paste.
Gradually add flour until the mixture is light.
Stir in a pinch of salt and sugar if desired.
Let the mixture stand for 1 hour to rise.
Bake
Preheat the oven to 350°F (175°C) and bake in tins until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and help bind the batter into a smooth, tender crumb.
- Yeast
- Produces gas as it ferments, lifting the mixture so the cakes rise and turn light.
- Flour
- Forms the structure that holds the risen batter and sets it as the cakes bake.
- Butter
- Adds fat for softness and flavor, contributing to a tender crumb and golden color.
- Warm milk
- Provides moisture and hydrates the flour, and warmth helps the yeast become active.
The step that matters
Letting the mixture stand to rise. The yeast needs time and mild warmth to ferment and produce gas. Under-proofed batter stays dense, while over-proofed batter can collapse or turn sour, so the rise should be watched rather than just timed.
