Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Rich Pound Cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 300°F (150°C).
Make the batter
In a large bowl, beat the butter until creamy.
Gradually add the powdered sugar and continue beating.
Add the flour, then the beaten egg yolks, and mix well.
Stir in the grated lemon rind, chopped candied peel, currants, and sultanas.
Gently fold in the beaten egg whites.
Bake
Butter a cake tin, pour in the mixture, and bake for 2 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and gives the cake its rich, tender crumb.
- Eggs
- Yolks add richness and binding, while whipped whites lighten the batter and help it rise.
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Powdered sugar
- Sweetens the batter and dissolves easily into the creamed butter for a smooth texture.
- Currants
- Add chewy pockets of fruit sweetness throughout the cake.
The step that matters
Folding in the egg whites. Egg whites hold air that gives lift. Stirring them in vigorously deflates the batter, so fold gently with a spatula until just combined, keeping the air in the mixture.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, egg, butter, lemon):

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