Why it works: Butter and flour 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 good oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the butter into a cream in a warm pan.
Add sifted sugar and beat until well combined.
Add the eggs one at a time, beating for 20 minutes.
Stir in the flour and currants, and add flavoring to taste.
Bake
Bake in a well-lined tin for 1 hour at 350°F (175°C).
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
- Castor sugar
- Sweetens the cake and, beaten with butter, traps air for a lighter crumb.
- Butter
- Adds fat for a tender texture and rich flavor.
- Eggs
- Bind the batter, add moisture, and give structure as the cake sets.
- Flour
- Forms the framework that holds the cake's crumb together.
- Baking powder
- Releases gas during baking so the cake rises.
The step that matters
Adding the eggs one at a time. Eggs must be added gradually so the butter and sugar mixture stays a stable emulsion. Adding them too quickly can make the batter curdle, which can leave a coarser, denser cake.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Currantthe original
Fit is the average pairing score against sugar, butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
