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.
Make the dough
Mix the milk, yeast, and egg together.
Add the flour and knead to form a dough.
Set the basin in a warm place and cover with a cloth to let the dough rise for 1 to 2 hours.
Shape and rise
Add the fruit and shape into buns.
Place the buns on buttered baking sheets to rise for 1 hour.
Bake
Brush the buns lightly with milk, score a cross on top with the back of a knife, and bake at 400°F (200°C) for 15 to 20 minutes.

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 dough's gluten structure that traps gas and holds the buns' shape.
- Yeast
- Produces carbon dioxide as it ferments, making the dough rise and become light.
- Butter
- Adds fat that tenderises the crumb and enriches the flavour of the dough.
- Milk
- Provides moisture for hydrating the flour and softening the dough; also aids browning on top.
- Eggs
- Add richness, moisture, and structure, helping the dough set and brown in the oven.
- Castor sugar
- Feeds the yeast and adds sweetness, helping the crust brown during baking.
The step that matters
Let the dough rise fully in a warm place. Yeast needs time and warmth to produce enough gas for a light, airy crumb. Under-proofed dough bakes dense, while over-proofed dough can collapse and lose structure.
Swap the currant

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