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 ↓
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 flour, sugar, currants, mixed spices, and salt together.
Soak yeast in warmed milk; add enough flour mixture to make a thin batter.
Cover and set in a warm place until light.
Add melted butter, remaining flour, and enough milk to form a soft paste.
Cover and let rise until light.
Shape and bake
Shape dough into buns and place them on buttered tins; let rise until light.
Press a cross mold on each bun 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 gluten network that traps gas and gives the buns their structure.
- Yeast
- Produces carbon dioxide gas as it ferments, making the dough rise and turn light.
- Butter
- Adds fat that tenderises the crumb and gives the buns richness.
- Sugar
- Feeds the yeast and adds sweetness and browning during baking.
- Milk
- Hydrates the flour and yeast, forming the dough and adding softness.
The step that matters
Letting the dough rise until light. Yeast needs warmth and time to produce enough gas for a light texture. Under-proofed dough bakes dense, while over-proofed dough may collapse in the oven.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, milk, butter):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, sugar, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
