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 ↓
Fresh Blackberry Pie
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Line a pie pan with a flaky pie crust, ensuring the bottom is floured.
Fill and cover
Mix the blackberries, sugar, and flour together.
Place the mixture in the lined pan and dot with butter on top.
Cover the pie with a full crust or create a lattice with strips of pastry.
Bake and serve
Bake for 10 minutes, then reduce the heat to 300°F (150°C) and continue baking until done.
Serve with a generous spoonful of whipped cream on each piece.

Flour and butter 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
- Blackberries
- Provide the main fruit filling, giving the pie its flavour and juicy body.
- Flour
- Thickens the fruit juices so the filling sets rather than running out.
- Sugar
- Sweetens the filling and balances the tartness of the blackberries.
- Butter
- Adds richness and fat to the top of the filling as it bakes.
The step that matters
Bake until done after reducing the heat. Blackberries release a lot of juice as they heat. The filling needs enough time at the lower temperature for the flour to thicken those juices, otherwise the pie can be runny when cut.
“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.
