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).
Make the batter
In a bowl, mix the flour, butter, sugar, and grated orange rind until well combined.
Beat the egg and stir it into the mixture along with the orange juice.
Add enough buttermilk to create a smooth, thick batter.
Bake
Half fill small greased tins with the batter.
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 structure and a nutty, earthy flavour as the batter sets.
- Butter
- Adds fat for tenderness and a rich flavour in the crumb.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
- Egg
- Binds the batter and helps it set into a firm crumb.
- Orange rind
- Contributes aromatic orange oils that flavour the batter.
- Buttermilk
- Adds moisture and acidity that give the batter a smooth, tender texture.
The step that matters
Half fill the tins. Small tins need only partial filling because the batter rises in the oven. Filling them too full can cause overflow and a dense, unevenly cooked centre.
Swap the orange
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, buttermilk):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against flour, butter, sugar, egg, buttermilk. Candidates are from the same food group and used in at least 100 recipes.
