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 sponge
Dissolve the yeast in warm water.
Combine milk and enough flour to make a thick batter; set aside overnight.
In the morning, add melted butter, sugar, grated nutmeg, and salt to the batter.
Shape and bake
Add sufficient flour to form a soft dough.
Shape the dough into balls, flatten them, and mark a cross on top with a knife.
Place on buttered tins and let rise until light.
Bake at 400°F (200°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Ferments the dough, producing gas that makes the buns rise and become light.
- Flour
- Forms the gluten network that gives the dough its structure once kneaded into a dough.
- Milk
- Adds moisture and richness, softening the crumb and aiding browning.
- Butter
- Adds fat, tenderizing the crumb and adding flavour.
- Sugar
- Feeds the yeast and adds sweetness, helping the crust brown in the oven.
The step that matters
Letting the batter rest overnight. The long slow rest lets the yeast ferment the batter, developing flavour and an active starter that the dough needs to rise well.
Swap the coriander
The recipe marks coriander as optional. How well each one fits the dish's main ingredients (milk, flour, butter, sugar, nutmeg):
- Cinnamonfits better
- Cardamomfits better
- Allspicefits better
- Corianderthe original
Fit is the average pairing score against milk, flour, butter, sugar, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
