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 ↓

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 large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Gradually add the flour and mix until just combined.
Fold in the currants and grated lemon rind if using.
Bake
Spoon the batter into buttered small tin pans.
Bake for about 20 minutes or until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving a light, tender crumb and rich flavor.
- Eggs
- Add structure and richness, and help bind the batter as it sets in the oven.
- All-purpose flour
- Provides the structure that sets the cakes as the batter bakes.
- Granulated sugar
- Sweetens the batter and helps create a light, creamed texture with the butter.
- Currants
- Add bursts of sweetness and chewy fruit texture throughout the cakes.
The step that matters
Creaming the butter and sugar. Beating butter and sugar until light and fluffy traps air that expands in the oven. Under-creaming leaves a dense cake, while adding eggs too quickly can cause the batter to curdle.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (flour, butter, egg, sugar, currant):

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