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
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix flour, baking powder, and salt.
Cut in the butter until the mixture resembles coarse crumbs.
Stir in the milk until just combined.
Divide the dough in half and shape into two layers.
Bake and assemble
Bake for 15-20 minutes until golden.
While baking, mix peaches with sugar and let sit.
Once baked, layer peaches between the biscuit layers.
Serve with whipped cream.

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 main structure of the biscuit layers as gluten develops with mixing.
- Unsalted butter
- Stays cold in cubes so it creates flaky layers as it melts in the oven.
- Baking powder
- Releases gas in the dough so the biscuit layers rise and become light.
- Milk
- Hydrates the flour so the dough holds together and bakes tender.
- Peaches
- Add moisture and fruity sweetness that soak into the layers.
- Heavy cream
- Adds richness and a soft, cool topping when whipped.
The step that matters
Cut in the butter until coarse crumbs form. Cold butter pieces stay separate in the dough and melt during baking, leaving steam pockets that make flaky layers. If the butter softens or is overworked into the flour, the biscuits turn dense and tough.
