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 Shortcake
Ingredients
Directions
Make the dough
In a bowl, mix the flour, baking powder, salt, and sugar thoroughly.
Add the butter and enough milk to form a soft dough.
Roll out the dough into two crusts.
Place one crust on a baking sheet, butter it slightly, and then place the second crust on top.
Bake until golden and partially cool.
Assemble and serve
Separate the crusts and place the bottom crust on a platter.
Cover the bottom crust with a layer of sliced peaches and sprinkle with sugar.
Top with the second crust and add more peaches on top.
Serve warm with sweetened cream.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the structure of the dough so the crusts hold together under the fruit.
- Baking powder
- Releases gas in the dough, helping the crusts rise and turn light rather than dense.
- Butter
- Adds fat that tenderizes the crust and helps it brown as it bakes.
- Peaches
- Provide juicy fruit and natural sweetness that moistens the layers between the crusts.
The step that matters
Bake until golden and partially cool. Baking until golden sets and browns the crust, while partial cooling lets it firm up so it can be split without crumbling. Under-baking leaves a gummy, fragile crust that breaks when separated.

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