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 ↓
Small Plum Cakes
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the dough
Mix the flour and sifted sugar in a bowl.
Rub in the butter until well combined.
Add the currants and eggs, mixing until smooth.
Shape and bake
Roll out the mixture thinly and cut into small round cakes using a wine glass.
Bake in a moderate oven (350°F / 175°C) until golden.

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
- Flour
- Provides the structure that holds the cakes together as they bake.
- Sifted sugar
- Adds sweetness and helps give the cakes a tender crumb.
- Butter
- Adds fat, which makes the cakes rich and tender.
- Eggs
- Bind the mixture and add structure and richness.
- Currants
- Add fruitiness and sweetness, and moisture as they plump during baking.
The step that matters
Roll out the mixture thinly. A thin, even layer lets the cakes bake through and brown evenly. Thick or uneven pieces can stay doughy in the middle while the edges over-brown.
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.
