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.
Make 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.
Beat the egg whites in a separate bowl until stiff peaks form.
Combine the flour and baking powder in another bowl.
If using cream of tartar, mix it with the flour; if using baking soda, mix it with the milk.
Gradually add the flour mixture to the butter mixture, alternating with the milk.
Fold in the beaten egg whites gently.
Add lemon extract to taste and mix well.
Bake and assemble
Divide the batter among four flat baking tins.
Bake for about 15‑20 minutes or until golden and a toothpick comes out clean.
Once cooled, layer with jelly or custard and top with moistened coconut.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and add richness; whipped whites lighten the batter and help it rise.
- All-purpose flour
- Provides the structure that sets the cake as it bakes.
- Butter
- Adds fat for tenderness and flavour, and creaming traps air in the batter.
- Sugar
- Sweetens the cake and helps it brown while creaming aerates the batter.
- Baking powder
- Releases gas in the batter so the cakes rise and become light.
- Milk
- Adds moisture and helps form a smooth, pourable batter.
The step that matters
Folding in the beaten egg whites. Egg whites hold air only while whipped; stirring them in vigorously knocks the air out, so fold gently to keep the cakes light.
