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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a large bowl, combine milk or water and yeast.
Add moist sugar, butter, and coarse sea salt.
Gradually mix in enough flour to form a soft dough.
Knead the dough until smooth and let it rise until doubled in size.
Shape and bake
Divide the dough into pieces weighing 4 oz each.
Shape each piece into a bun and make a cross on top.
Brush the buns with beaten egg and let them rise again.
Bake in a moderate oven at 350°F (175°C) until golden brown.

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 gluten network that gives the dough its structure and chew.
- Yeast
- Produces carbon dioxide as it ferments, making the dough rise and become airy.
- Butter
- Adds fat that tenderizes the crumb and gives a rich, soft texture.
- Moist sugar
- Feeds the yeast and adds sweetness, and helps the crust brown in the oven.
- Egg
- Brushed on top, it promotes a glossy, deep golden browned crust.
The step that matters
Let the dough rise until doubled. Yeast needs enough time to ferment and build gas bubbles; underproofed dough bakes dense, while the rise also develops the gluten that gives the buns their structure.
Swap the currant
How well each one fits the dish's main ingredients (milk, sugar, butter, flour, egg):

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