Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a bowl, beat together the butter, sugar, and egg yolks.
Add the cream and mix well.
Sift the flour with the baking powder and add it to the mixture.
Beat the egg whites until stiff and fold them into the batter.
Add the currants and mix until well combined.
Bake
Pour the batter into flat tins and bake for 20 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Eggs
- Egg yolks enrich the batter and whipped whites lighten it, giving a tender, airy crumb.
- Butter
- Fat that adds richness and a tender texture to the batter.
- Flour
- Forms the structure that holds the buns together as they bake.
- Baking powder
- Releases gas during baking so the buns rise and become lighter.
- Sugar
- Sweetens the batter and helps it brown during baking.
- Currants
- Add fruity sweetness and small bursts of chewy texture throughout the buns.
The step that matters
Folding in the beaten egg whites. Stiff whites hold air that lightens the batter. Overmixing when folding deflates them, which leads to dense buns.

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