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 ↓
Phach Short Cake
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.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix the flour, baking powder, butter, and salt.
Add the beaten egg yolks and enough milk to form a soft dough.
Roll out the dough to fit a high pan and split it with a hot knife.
Assemble and serve
Spread the bottom crust with butter and layer with the quartered peaches.
Dust with pulverized sugar and place the second crust on top.
Spread whipped cream over the top and add halved, pared fruit.
Dust with more pulverized sugar before serving.

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 dough so the crusts hold their shape.
- Baking powder
- Releases gas in the oven so the crusts rise and stay tender.
- Butter
- Adds fat that makes the crust short and rich in texture.
- Egg yolks
- Add richness and help bind the dough together.
- Peaches
- Provide moisture and natural sweetness between the crusts.
The step that matters
Splitting the dough with a hot knife. A hot knife cuts through the baked crust cleanly, so the layers separate without crumbling or tearing. Cutting it cold can squash the soft layers and make the split uneven.

Fit is the average pairing score against flour, butter, egg, milk, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
