Why it works: Flour and butter 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 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.
Assemble
Line a pie pan with the crust.
Fill the crust with ripe raspberries.
Sprinkle sugar over the berries, adjusting to their sweetness.
Dredge flour and add small bits of butter on top.
Close and bake
Wet the edge of the crust, place the upper crust on, and pinch the edges together.
Prick holes in the upper crust to allow air to escape.
Bake at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raspberries
- Provide the main filling, supplying fruit flavour, moisture and tartness that the sugar balances.
- Sugar
- Sweetens the berries and helps draw out juice that thickens into the filling.
- Flour
- Absorbs the berry juices as they cook, thickening the filling so it holds its shape when sliced.
- Butter
- Adds richness and fat to the filling, softening the tart berry flavour.
The step that matters
Sprinkle sugar, adjusting to sweetness. Berries vary in sweetness and tartness, so tasting them first prevents a filling that is too sour or too sweet. Sugar also draws out juice, which the flour must thicken.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
