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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
Scald the milk.
Add the butter to the milk.
Set the mixture aside to cool.
When lukewarm, add the yeast, salt, sugar, and flour to the mixture.
Beat steadily for 5 minutes.
Cover and set in a warm place for 2 hours to rise until very light.
Add the eggs and bake
In a separate bowl, beat the yolks until very light. Add the yolks to the batter.
In a separate bowl, beat the whites until very light. Gently fold in the whites.
Set the batter in a warm place for 15 minutes to rise.
Pour the mixture into a well-greased turk's head mold.
Bake at 400°F (200°C) for 40 minutes.
Serve hot.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Flour
- Forms the gluten network that gives the bun its structure.
- Eggs
- Yolks add richness and tenderness, while whipped whites lighten the batter.
- Yeast
- Produces gas that makes the batter rise and turn light.
- Butter
- Adds fat that softens the crumb and gives a tender texture.
- Milk
- Provides moisture and liquid that hydrates the flour.
The step that matters
Folding in the whites. Whipped egg whites hold air that lightens the batter. Stirring them vigorously deflates that foam, so fold in gently with a spatula until just combined.
