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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a basin, mix flour and yeast with warm milk.
Let the mixture rise in a warm place.
Once risen, mix in eggs, egg yolks, cold butter, and salt with your hand.
Shape and bake
Butter some tea cups and fill them half full with the mixture.
Let them rise until nearly full.
Bake in a hot oven at 400°F (200°C).

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.

Flour and butter 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 structure that holds the dough together and lets it rise.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Eggs
- Add structure and richness, and help the buns set and brown as they bake.
- Egg yolks
- Add richness, fat and colour, giving a tender crumb and golden crust.
- Cold butter
- Adds fat and richness, contributing to a tender texture and flavour.
The step that matters
Letting the dough rise until nearly full. Yeast needs warm conditions and enough time to create gas; under-proofed dough bakes dense, while over-proofed dough can collapse or lose structure in the hot oven.
“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.
