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 ↓
Fruit 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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Mix the flour and baking powder together.
Rub in the butter until well combined.
Add the sugar and mix well.
Beat the eggs with a little milk.
Combine the egg mixture with the dry ingredients and mix thoroughly.
Stir in the sultanas, currants, and mixed peel.
Bake
Pour the batter into a cake tin lined with well-buttered paper.
Bake for about two hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure of the cake as its gluten and starch set during baking.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Baking powder
- Releases gas in the batter so the cake rises and becomes lighter.
- Castor sugar
- Sweetens the cake and helps create a tender texture and browning.
- Sultanas
- Add sweetness, moisture and chewy texture throughout the cake.

Fit is the average pairing score against flour, sugar, egg, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
