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 ↓
Little Plum Cakes
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.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a bowl, mix the flour and sugar together.
Beat the butter until creamy, then add the beaten eggs.
Stir in the currants, then add the flour and sugar mixture.
Mix until well combined; the batter should be stiff.
Bake and serve
Dredge flour on baking sheets and drop batter by the walnut-sized portions.
Bake in the preheated oven until golden.

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.

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
- All-purpose flour
- Provides the structure that holds the cakes together as they bake.
- Butter
- Adds richness and tenderness, and creaming it traps air that helps the cakes rise.
- Eggs
- Bind the batter and set during baking to give the cakes structure.
- Sugar
- Sweetens the cakes and helps them brown as they bake.
- Currants
- Add concentrated sweetness and chewy bursts of fruit throughout the cakes.
The step that matters
Keep the batter stiff. A stiff batter holds its shape when dropped onto the sheets. If the batter is too loose, the cakes spread out thin and lose their domed, cake-like texture.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
