Why it works: Cream and butter 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 ↓
Spanish Buns
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Cream the butter and sugar together until light and fluffy.
Beat the egg yolks until very light, then add to the butter mixture.
Wash, pick, and dry the currants, then flour them well and mix into the batter.
Beat the egg whites to stiff peaks and gently fold them into the mixture.
Sift in the baking powder and mix until just combined.
Bake
Bake in a preheated oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness and emulsify the batter, while whipped whites add air and lift.
- Butter
- Adds fat and tenderness, and creaming it with sugar traps air for a lighter crumb.
- Sugar
- Sweetens the batter and, creamed with butter, helps create a light texture.
- Flour
- Provides the structure that holds the buns together as they set in the oven.
- Baking powder
- Releases gas in the oven, causing the batter to rise.
- Cream
- Adds moisture and richness, softening the crumb.
The step that matters
Folding in the egg whites. Stiff egg whites hold air that gives the buns lift. Stirring or beating them in deflates that air, leaving a denser result, so fold gently and stop once no white streaks remain.
Swap the currant

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