Why it works: Flour and buttermilk are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Buttermilk Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Beat the butter until creamy.
Add the sugar and mix well.
Mix and bake
Stir in the flour, currants, candied lemon peel, and buttermilk until thoroughly combined.
Butter a cake tin and pour in the mixture.
Bake for 3.5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wholemeal flour
- Provides the main structure of the cake as it sets in the oven.
- Butter
- Adds richness and a tender crumb when beaten until creamy.
- Sugar
- Adds sweetness and helps give the cake a softer texture.
- Buttermilk
- Adds moisture and acidity that keeps the crumb tender.
- Currants
- Add fruit pieces and sweetness throughout the cake.
The step that matters
Bake for 3.5 hours. A long, low bake at 300°F lets the dense batter cook through to the centre without the outside browning or drying too quickly. Check that the middle is set before removing the cake from the oven.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, lemon, buttermilk):

- Currantthe original
Fit is the average pairing score against flour, sugar, butter, lemon, buttermilk. Candidates are from the same food group and used in at least 100 recipes.
