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.
Make the dough
Mix the flour, sugar, spice, and currants in a bowl.
Make a hole in the center.
Add yeast and warm milk. Mix to form a thin batter.
Cover the mixture. Let it rise in a warm place until it ferments.
Add melted butter and salt. Mix well.
Form a soft dough. Add more warm milk if necessary.
Cover with a clean cloth. Let it rise for about 1 hour.
Shape and bake
Shape the dough into buns.
Place them on greased baking sheets, leaving 3 inches between each. Let them rise for another 30 minutes.
Use the back of a knife to mark a cross on each bun.
Bake in a preheated oven 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
- Ferments the sugars and produces gas that makes the dough rise.
- Butter
- Adds fat that tenderizes the crumb and gives a richer texture.
- Sugar
- Feeds the yeast and adds sweetness and browning during baking.
- Currants
- Add fruit sweetness and chewy pockets throughout the buns.
- Warm milk
- Hydrates the flour to form the dough and adds richness and softness.
The step that matters
Letting the dough rise in a warm place. Yeast needs warmth to ferment well. Too cold and the dough rises slowly. Too hot and the yeast can die. Proper rising builds the gas and gluten structure that give the buns a light, open crumb.
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.
