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 ↓

Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a mixing bowl, cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the currants and candied lemon-peel.
In a separate bowl, combine the flour and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Add milk as needed to achieve a batter that can be poured.
Bake
Pour the batter into a greased baking pan and bake for 30-40 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cake a light, tender crumb and rich flavour.
- Eggs
- Add structure and richness, binding the batter as it sets in the oven.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking soda
- Reacts with the batter to produce gas, helping the cake rise.
- Sugar
- Sweetens the cake and helps create a light, aerated creamed base.
The step that matters
Adding the dry ingredients to the wet mixture. Mixing only until just combined keeps the batter tender. Overmixing develops gluten in the flour, which can make the cake tough and dense.
Swap the currant
