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 ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 400°F (200°C).
Beat the butter until creamy.
Rub the flour and baking powder into the butter.
Mix in the currants, sugar, candied peel, and a few drops of vanilla.
Beat the eggs with the milk and combine with the mixture to form a dough.
Shape and bake
Drop spoonfuls of the dough onto a buttered baking dish.
Bake for 15 minutes.

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 main structure as its proteins and starch set during baking.
- Butter
- Rubbed into the flour, it coats flour particles and keeps the bun texture tender and crumbly.
- Eggs
- Bind the dough together and add structure and richness as they set in the oven.
- Baking powder
- Releases gas when heated and moistened, lifting the buns so they rise.
- Sugar
- Adds sweetness and helps the tops brown in the oven.
The step that matters
Combining the eggs and milk with the dry mixture. Mix only until the dough just comes together. Overworking develops gluten in the flour, which makes the buns tough and dense instead of light and short.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, milk):

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