Why it works: Sugar and flour 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 ↓
Old-fashioned Plum Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Seed the ripe plums and place them in a deep pie plate lined with puff pastry.
Assemble and bake
Sprinkle a thick layer of sugar over each layer of plums.
Add spices if desired.
Add 1 tablespoon of water and sprinkle a little flour over the top.
Cover with a thick crust and bake for 50 to 60 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe plums
- Provide the main fruit filling, supplying juice and tart-sweet flavor as they cook.
- Sugar
- Sweetens the filling and draws out juice from the plums as it sits and cooks.
- Flour
- Sprinkled over the filling to thicken the juices as the pie bakes.
- Rich puff pastry
- Forms the buttery, flaky lining and top crust that encloses the filling.
The step that matters
Sprinkling flour over the filling. Flour must be spread evenly over the juicy plums so it can thicken the liquid during baking. Clumps or too little flour can leave a runny or pasty filling.
Swap the plum

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