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 ↓
Delicious Prune Pie
Ingredients
Directions
Make the crust
Make a crust by mixing flour and butter, adding a little cold water as needed.
Roll out the crust, then dot with 1 tablespoon of butter in small pieces.
Fold the crust and refrigerate for 30 minutes before using.
Make the filling
Scald the prunes, then boil them with sugar and fruit juice until tender.
Remove the pits from the prunes, then mix in chocolate and additional juice.
Assemble
Cover the filling with narrow strips of crust, crossing them over each other.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the structure of the crust that holds the filling.
- Butter
- Adds richness and tenderness to the crust and helps it flake when kept cold.
- Prunes
- Form the main filling and contribute sweetness and soft texture as they cook.
- Sugar
- Sweetens the prune filling and helps it thicken as it cooks.
- Fruit juice
- Adds moisture and fruity flavor to the filling as the prunes soften.
- Chocolate
- Adds deep, rich flavor to the prune filling.
The step that matters
Chilling the folded crust. Cold butter stays in solid pieces, and as it melts in the oven it creates steam pockets that make the crust flaky. Refrigerating firms the dough so it holds its shape and does not become greasy or tough.
