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 Cream Tarts
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix butter, drippings, and salt.
Gradually add flour until well combined.
In a separate bowl, mix ice water, whole egg, egg yolks, and brown sugar.
Add this mixture to the flour and sift in baking powder.
Handle the dough minimally and form into round rings.
Bake and serve
Bake until light brown.
Dust with powdered sugar and fill the center with peach compote.
Top with whipped cream or ice cream.

Butter and flour 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
- Butter
- Adds fat that keeps the pastry tender and flaky as it bakes.
- Flour
- Forms the main structure of the dough once it is mixed with liquid.
- Egg yolks
- Add richness and help bind the dough.
- Whole egg
- Binds the dough and adds moisture for structure.
- Baking powder
- Releases gas during baking so the pastry rises and lightens.
- Brown sugar
- Adds sweetness and helps the pastry brown during baking.
The step that matters
Handle the dough minimally and form into round rings.. Overworking flour-based dough develops gluten, making the tarts tough instead of tender. Keeping the dough cold and handling it briefly preserves a light, flaky texture.

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