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 ↓
Raspberry Pies, with Covers
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).
Cover a pie plate with the pie crust.
Fill the crust with raspberries.
Add sugar, butter, and flour to the raspberries.
Cover the pie with another crust and cut a slit in the center.
Bake and serve
Bake gently until the pie is fully cooked.
Let the pie stand for a few minutes after baking before serving.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Raspberries
- Provide the main fruit filling, supplying flavor, color, and moisture that cooks into the pie.
- Sugar
- Adds sweetness and helps draw moisture from the berries to form the filling.
- Flour
- Thickens the juices released by the raspberries so the filling sets rather than running.
- Butter
- Adds richness and fat, contributing flavor and a tender mouthfeel to the filling.
- Pie crust
- Forms the structure that holds the filling and browns in the oven.
The step that matters
Bake gently until fully cooked. Raspberries release a lot of liquid, and the flour needs sustained heat to gelatinize and thicken it. Underbaking leaves a runny filling and a soggy bottom crust, while overly high heat can scorch the top before the center sets.
