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 ↓
Peach Short 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).
In a bowl, cream the butter and sugar together.
Add the eggs and milk, mixing well.
In another bowl, combine the flour and baking powder, then gradually add to the wet mixture.
Pour the batter into a greased baking dish and bake until golden.
Assemble and serve
While the cake is baking, heat the sliced peaches in a separate bowl.
Once the cake is done, split it in half and spread a little butter on each layer.
Fill the layers with the heated peaches and top with more peaches.
Serve warm with whipped cream on top, if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and turns light.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Butter
- Adds richness and tenderness to the cake and its layers.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
- Milk
- Moistens the batter so it bakes into a tender crumb.
The step that matters
Gradually adding the flour mixture to the wet mixture. Adding flour gradually and mixing only until combined keeps the batter smooth and limits gluten development, which would otherwise make the cake tough and dense.
