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 ↓
Hot Cross Buns
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
Rub the butter into the flour.
In a warm bowl, mix half of the flour with the yeast and warm milk, then add the sugar.
Pour this mixture into the bowl with the remaining flour and mix well.
Let the mixture rise in a warm place for about 30 minutes.
Add the currants, sultanas, and candied peel, then knead into a dough.
Set aside to rise for 45 minutes.
Shape and bake
Once risen, knead the dough again and divide it into 3 oz portions.
Shape the portions into buns and place them on warm baking tins so they touch.
Mark a cross on each bun with a knife and allow to rise again.
Bake in a hot oven at 400°F (200°C) for about 15 minutes.

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 dough its structure and chew.
- Yeast
- Ferments sugars to produce gas, making the dough rise and become light.
- Butter
- Adds fat that tenderises the crumb and enriches flavour.
- Milk
- Provides liquid to hydrate the flour and add richness and browning through milk sugars.
- Sugar
- Feeds the yeast and adds sweetness and browning to the crust.
- Currants
- Add fruit sweetness and moisture to the dough.
The step that matters
Letting the dough rise fully. Yeast needs time and warmth to produce enough gas for a light, airy bun. Under-proofed dough bakes dense, while over-proofed dough can collapse and lose structure.
Swap the currant
How well each one fits the dish's main ingredients (butter, milk, flour, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against butter, milk, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
