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 ↓
Orange Sandwich
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.
Make the batter
In a bowl, mix flour and sugar.
Rub in the butter.
Add baking powder, orange rind, and beaten eggs.
Stir in the orange juice; add a little milk if necessary.
Beat the mixture well and pour it into a greased sandwich tin.
Bake and fill
Bake for about 30 minutes at 350°F (175°C).
Once cooled, cut the cake in half and spread with orange butter.

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 crumb.
- Butter
- Adds fat for a tender texture and rich flavour.
- Eggs
- Bind the batter and add structure and richness.
- Baking powder
- Releases gas in the oven so the cake rises.
- Sugar
- Sweetens the cake and helps brown the crust.
- Orange rind
- Adds aromatic orange oil flavour to the batter.
The step that matters
Beat the mixture well. Thorough beating combines the eggs and fat evenly and traps air in the batter, which helps the cake rise and gives an even crumb. Undermixing can leave streaks or a dense texture.
Swap the orange
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against flour, sugar, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
