Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Peach Tart
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 crust
Preheat the oven to 400°F (200°C).
Rub the butter into the flour and sugar.
Add the egg yolks and mix well with a knife.
Gradually add enough ice water to form a firm, dry paste.
Roll out the paste to about ¼ inch thick.
Line a pie dish (at least 1 inch deep) with the paste and trim the edges.
Bake the empty crust for 10 to 12 minutes.
Prepare and assemble
Prepare the peaches by peeling, halving, and stewing them with sugar until transparent.
Fill the baked tart crust with the peaches, overlapping the halves.
Pour some syrup over the peaches and serve with a pitcher of cream.

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 paste once mixed with butter and liquid.
- Butter
- Adds fat that keeps the crust tender and flaky as it bakes.
- Egg yolks
- Add richness and help bind the paste together.
- Ice water
- Brings the dough together while keeping it firm and cool.
- Peaches
- Provide the fruit flavor and moisture of the filling.
- Sugar
- Sweetens the crust and stewed peaches and helps form a syrup.
The step that matters
Gradually add enough ice water to form a firm, dry paste. Too much water develops gluten and makes the crust tough, while cold water keeps the butter solid so the pastry stays flaky. Adding it gradually lets you stop once the dough just holds together.
