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 ↓
Sandwich Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 400°F (200°C).
Cream the butter and sugar together until light and fluffy.
Add the egg yolks and mix well.
In a separate bowl, combine the flour and baking powder.
If using, mix the cream of tartar into the flour.
If using, mix the baking soda into the milk.
Combine all ingredients.
Add lemon extract to taste.
Beat well for a few minutes.
Bake and assemble
Divide the batter into four flat tins.
Bake until golden.
Once cooled, layer with jelly or custard.
Sprinkle with moistened coconut.
Ice the top as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness and moisture, while whites moistened coconut for the topping.
- Baking powder
- Releases gas in the batter, causing the cake layers to rise and become light.
- Flour
- Forms the structure that holds the cake layers together.
- Butter
- Adds fat that tenderises the crumb and carries flavour.
- Sugar
- Sweetens the batter and helps it brown in the oven.
The step that matters
Beat well for a few minutes. Beating the creamed butter, sugar and eggs traps air that helps the layers rise. Under-beating leaves a dense crumb, while the batter should be combined without overworking the flour.
Swap the lemon

Fit is the average pairing score against sugar, butter, cream, egg, flour, milk, coconut. Candidates are from the same food group and used in at least 100 recipes.
