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 ↓

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).
In a bowl, mix the flour, butter, sugar, and grated orange rind until well combined.
Beat the egg, then stir it into the mixture along with the orange juice.
Add enough buttermilk to create a smooth, thick batter.
Half fill small greased tins with the mixture.
Bake
Bake for 15 minutes.

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 as its proteins and starches set during baking.
- Butter
- Adds fat that tenderises the crumb and carries flavour.
- Sugar
- Adds sweetness and helps the cake brown at the edges.
- Orange rind
- Adds aromatic citrus oils that give the cake its fresh orange flavour.
- Orange juice
- Adds moisture and bright acidity that balances the sweetness.
- Buttermilk
- Adds moisture and acidity, helping the batter stay soft and tender.
The step that matters
Adding the buttermilk. Add it gradually until the batter is smooth and thick. Wholemeal flour absorbs liquid slowly, so too much buttermilk at once makes the batter runny and can bake up dense or uneven.
Swap the orange
How well each one fits the dish's main ingredients (flour, butter, sugar, buttermilk):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against flour, butter, sugar, buttermilk. Candidates are from the same food group and used in at least 100 recipes.
