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 gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Dissolve the yeast in the tepid water.
Add the dissolved yeast to the scalded and cooled milk.
Mix in the butter, sugar, salt, and nutmeg.
Add enough flour to make a stiff batter and cover it.
Set the batter in a warm place to rise.
Once risen, add enough flour to roll out like biscuit dough.
Shape and proof
Roll out to ½ inch thick and cut with a biscuit cutter.
Place on greased tins, cover, and let stand until light again.
Make a deep cross on the top of each bun with a knife.
Bake and glaze
Bake in a preheated oven at 400°F (200°C) for 20 to 25 minutes.
When done, brush the tops with a mixture of 1 beaten egg white and 1 tablespoon powdered sugar.

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 structure of the dough, and its gluten traps gas so the buns rise and hold their shape.
- Yeast
- Produces carbon dioxide as it ferments sugars, making the dough rise and become light.
- Milk
- Adds moisture and richness, and its proteins help give the bun a soft, tender crumb.
- Butter
- Adds fat that tenderizes the crumb and gives a softer, richer texture.
- Sugar
- Feeds the yeast and adds sweetness and browning in the baked crust.
- Baking soda
- Reacts with acidity in the batter to release gas and add lift.
The step that matters
Letting the dough rise fully before baking. Yeast needs time and warmth to produce enough gas for a light texture. Under-proofed buns stay dense and may collapse or split oddly in the oven, while the gluten network needs time to relax and expand.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, sugar, butter, flour):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against milk, sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
