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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Shape and bake
Combine the plain roll dough, 3 eggs, ¼ pound of butter, and 2 pounds of currants in a bowl.
Mould the mixture into round balls and place them on greased baking sheets.
Bake in a preheated oven at 350°F (175°C) until golden brown.
Glaze and finish
In a separate bowl, mix 1 cup of milk with a small handful of sugar and 2 eggs.
Brush the milk mixture over the baked buns.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and enrich it, giving a firmer, richer structure.
- Butter
- Adds fat that tenderises the crumb and carries flavour.
- Currants
- Add sweetness and chewy pockets of fruit throughout the dough.
- Milk
- Adds moisture to the dough and helps the glaze brown and shine.
- Sugar
- Adds sweetness and helps the crust brown during baking.
The step that matters
Bake until golden brown. Browning comes from the Maillard reaction and caramelisation of sugars in the crust. Stopping too early leaves pale buns with a doughy centre, so the golden colour is the cue that the bake is done.
Swap the currant
How well each one fits the dish's main ingredients (egg, butter, milk, sugar):

- Figfits better
- Coconutfits better
- Currantthe original
Fit is the average pairing score against egg, butter, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
