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 ↓

Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Cream the butter into the flour and add a pinch of salt.
Mix the yeast with the milk and set the sponge to rise.
After nearly an hour, work the sponge into a light dough.
Add the beaten egg and a little lukewarm milk.
Incorporate sugar, currants, and chopped candied lemon if desired.
Rise and bake
Cover the bowl with a cloth and let it rise by the fire for about half an hour.
Shape the dough into rolls and brush them with beaten egg.
Bake in a preheated oven at 400°F (200°C) for twenty minutes or more.

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 structure of the dough that holds the rise and shape of the rolls.
- Yeast
- Produces gas through fermentation, making the dough rise and become light.
- Butter
- Adds fat that softens the crumb and gives the rolls a richer texture.
- Egg
- Adds structure and richness, and the brushed egg helps the crust brown.
- Milk
- Hydrates the flour to form the dough and supports the yeast's activity.
The step that matters
Letting the sponge rise before adding the rest. The yeast needs time to ferment the sponge; working the dough before it has risen well can leave the rolls dense instead of light.
Swap the currant
How well each one fits the dish's main ingredients (butter, flour, milk, egg, sugar, lemon):

- Figfits better
- Currantthe original
Fit is the average pairing score against butter, flour, milk, egg, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
