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 ↓
A Good Light Bun
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Break the butter into small pieces and mix it with the flour.
Stir the yeast into the warm milk and add it to the flour mixture.
Let the mixture rise in a warm place for about 1 hour, or until very light.
Whisk the eggs and mix in a few tablespoons of warm milk, then strain and add to the dough.
Mix in the sugar, currants, and lemon rind (or nutmeg or candied orange rind).
Let the dough rise again for 1 hour.
Shape and bake
Beat the dough lightly with a wooden spoon, then transfer it to a buttered pan.
Bake in a preheated oven at 400°F (200°C) for nearly 1 hour.

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 bun together as the dough rises and bakes.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Eggs
- Add richness and help set the crumb as the bun bakes.
- Butter
- Adds fat for tenderness and a rich flavour in the crumb.
- Pale brown sugar
- Adds sweetness and helps the crust brown during baking.
- Currants
- Add sweetness and fruity bursts of flavour throughout the bun.
The step that matters
Let the dough rise until very light. Yeast needs a warm place and enough time to produce gas; under-proofed dough bakes dense because the gas has not expanded the gluten network enough to lift the bun.

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