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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Start the dough
Dissolve the yeast in 1 cup of milk with 2 cups of flour and the salt.
Let the yeast mixture rise until light.
In a separate bowl, cream the sugar, butter, and egg yolks together.
Mix the creamed mixture with the flour.
Add the fruit to the mixture.
Stir in the yeast mixture and beat for 20 minutes.
Let the dough rise.
Shape and rise
Shape the dough into buns.
Let the buns rise overnight.
Bake
Preheat the oven to 400°F (200°C).
Bake the buns for 20 minutes.
Make German buns
For German buns, roll out the dough.
Spread the dough with butter.
Beat one egg and brush it over the butter.
Chop fruit and nuts.
Roll up the dough and cut.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Produces gas as it feeds, making the dough rise and become light.
- Flour
- Forms the gluten network that gives the buns their structure.
- Butter
- Adds richness and a tender crumb by coating the flour and fat in the dough.
- Egg yolks
- Add richness and help bind the creamed mixture into the dough.
- Sugar
- Adds sweetness and helps the crust brown in the oven.
- Milk
- Supplies moisture that hydrates the flour and activates the yeast.
The step that matters
Beating the dough after adding the yeast mixture. Beating develops the gluten in the flour, which gives the enriched dough the strength to trap gas and rise well.
Swap the currant
How well each one fits the dish's main ingredients (milk, butter, sugar, egg, flour):

Fit is the average pairing score against milk, butter, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
