Why it works: Butter and flour 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 Pot Pie
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Line the sides of a deep pot with a paste made from butter and flour.
Peel and slice the peaches, then sugar them to your taste.
Bake and serve
Fill the pot with the peaches and cover the top with the paste, leaving an opening in the middle for steam to escape.
Bake in a moderate oven at 350°F (175°C) until golden.
Let cool and serve with cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and helps the paste turn tender and flaky as it bakes.
- Flour
- Forms the paste structure that lines the pot and covers the filling.
- Peaches
- Provide the fruit filling, supplying moisture and fruity flavour as they cook.
- Sugar
- Sweetens the peaches and helps them develop flavour as they cook.
The step that matters
Leaving an opening in the paste. The opening lets steam escape while the fruit cooks. Without it, trapped steam can make the crust soggy and push the juices out unevenly.

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