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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Mix the flour and salt. Rub in the butter.
Dissolve the yeast with the sugar until liquid. Add the lukewarm water or milk and beaten eggs to the yeast mixture.
Combine the yeast mixture with the flour to form a batter.
Cover the bowl with a cloth and let the dough rise in a warm place for 2 hours.
Knead in the sugar, currants, and nutmeg.
Shape and bake
Shape the dough into buns and place them on baking trays with space between each.
Cut a cross on top of each bun and let them rise for 10 minutes.
Bake in a 400°F (200°C) oven until golden brown.

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
- Fine flour
- Provides the main structure that the dough builds around as it is mixed and risen.
- Butter
- Rubbed into the flour to add richness and a tender crumb to the buns.
- Fresh german yeast
- Produces gas as it ferments, making the dough rise and become airy.
- Eggs
- Add structure and richness, and help bind the dough together.
- Sugar
- Feeds the yeast and adds sweetness and browning to the crust.
- Currants
- Add fruit and sweetness throughout the buns.
The step that matters
Let the dough rise for 2 hours in a warm place. Yeast needs time and warmth to produce enough gas for the dough to expand. Under-proofed dough bakes up dense, while the warm spot keeps fermentation steady.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, sugar, milk, egg, nutmeg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, butter, sugar, milk, egg, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
