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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Mix the flour, baking powder, currants, and salt in a bowl.
Dissolve the sugar and melt the butter in the milk over gentle heat, then mix everything together lightly.
Shape and bake
Form the mixture into round cakes and place them on a greased baking sheet.
Bake in a hot oven at 400°F (200°C) for about 30 minutes.
Brush the tops with egg white immediately after removing from the oven for a glaze.

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
- Provides the structure that holds the buns together as they bake.
- Baking powder
- Releases gas during baking so the buns rise and become light.
- Butter
- Adds fat for tenderness and a richer flavour in the crumb.
- Sugar
- Adds sweetness and helps the crust brown during baking.
- Milk
- Supplies moisture that hydrates the flour and forms the dough.
The step that matters
Brushing the tops with egg white right after baking. The glaze is applied while the buns are hot so it sets into a shiny coating as it cools. Letting the buns cool first would leave the glaze dull and less adhered.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, sugar, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
