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 ↓
Ripe Fruit Cake
Ingredients
Directions
The book says “a steady hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream together the butter and sugar until smooth.
Beat in the eggs one at a time, mixing well after each addition.
Sift the flour and baking powder together, then add to the mixture.
Stir in the raspberries, red currants, peaches, and milk until combined.
Bake
Pour the batter into a lined shallow pan and bake at 400°F (200°C) for about 50 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender crumb and flavour.
- Eggs
- Provide structure as they set, and help bind the batter together.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas when heated, helping the cake rise and become light.
- Sugar
- Sweetens the cake and helps create a soft, moist texture when creamed with butter.
- Ripe raspberries
- Add moisture and fruity sweetness, along with tartness and flavour.
The step that matters
Creaming the butter and sugar until smooth. Beating air into the fat and sugar creates small air pockets that help the cake rise and give it a lighter texture. Under-creaming can leave a dense cake.
