Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Peach Short Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 350°F (175°C).
In a bowl, mix flour, baking powder, sugar, and salt.
Rub in the butter until the mixture resembles coarse crumbs.
Add the beaten egg and cold water, mixing until just combined.
Bake and assemble
Bake in layers until golden brown.
Once done, split the layers and pour melted butter over them.
Spread each layer with sweetened mashed peaches.
Serve with sauce or whipped 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
- Flour
- Forms the structure of the shortcake layers as it sets in the oven.
- Baking powder
- Releases gas during baking so the layers rise and stay tender.
- Butter
- Rubbed into the flour to create a crumbly, tender texture and richness.
- Egg
- Binds the dough and adds richness and structure to the baked layers.
- Peaches
- Provide moisture, fruity flavor, and sweetness between the layers.
The step that matters
Mixing the dough until just combined. Overmixing after the liquid is added develops gluten in the flour, which makes the shortcake tough instead of tender. Stop once the flour is just moistened.

- Figfits about as well
- Peachthe original
Fit is the average pairing score against flour, sugar, butter, egg, sauce. Candidates are from the same food group and used in at least 100 recipes.
