Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Common Plum Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a large bowl, combine the flour, butter, sugar, and currants.
Add enough milk to form a dough.
Mix in the home‑made yeast with the milk.
Rise and bake
Set the dough aside to rise until light.
Preheat the oven to 350°F (175°C).
Bake the risen dough in the oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the main structure that holds the cake together as it bakes.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Adds sweetness and helps the crust turn golden brown.
- Currants
- Add sweetness, fruity flavor, and chewy pockets through the cake.
- Milk
- Provides the moisture needed to bring the flour and fat into a dough.
- Home-made yeast
- Produces gas that makes the dough rise and become light.
The step that matters
Let the dough rise until light. Yeast needs time to produce gas that expands the dough. If it rises too little, the baked cake will be dense and heavy rather than light.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, sugar, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, butter, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
