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 ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
Beat the egg in a bowl.
Add the melted butter, sugar, and milk to the egg and mix well.
Sift in the flour and baking powder, then stir until combined.
Bake
Pour the batter into gem pans and bake for about 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the batter and adds structure as it sets in the oven.
- Flour
- Forms the main structure of the cake once baked.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Melted butter
- Adds fat for a tender crumb and rich flavor.
- Milk
- Provides moisture that hydrates the flour and keeps the crumb soft.
- Sugar
- Sweetens the cake and helps it brown lightly in the oven.
The step that matters
Stir the flour and baking powder only until combined. Once flour meets liquid, gluten begins to form, and overmixing toughens the batter. Stirring just until no dry flour remains keeps the cake tender and lets the baking powder release its gas for a good rise.
