Why it works: Flour and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Plum Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Line a pie pan with the rich pie crust.
Sprinkle a little flour and sugar over the bottom of the crust.
Fill the crust with seeded plums.
Fill and bake
Sprinkle 1 cup of sugar and 2 tablespoons of flour over the plums.
Cover with a top crust and bake in the preheated oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rich pie crust
- Forms the structure of the pie and, with its fat, gives a tender, flaky texture.
- Flour
- Thickens the plum juices so the filling sets rather than running out of the pie.
- Sugar
- Adds sweetness and draws moisture from the plums, helping the filling thicken.
- Plums
- Provide the main fruit flavor, tartness, and the juices that make up the filling.
The step that matters
Sprinkling flour and sugar over the plums before covering. Flour and sugar mixed into the fruit juices thicken the filling as it bakes. Without this layer, the juices can stay thin and run out of the crust, leaving a soggy bottom and a watery pie.
Swap the plum
How well each one fits the dish's main ingredients (flour, sugar):
- Raisinfits better
- Vanillafits better
- Blueberryfits better
- Plumthe original
Fit is the average pairing score against flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
