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 ↓
Elderberry Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Assemble
Line a pie plate with the crust.
Fill with elderberries and sprinkle with sugar.
Add vinegar and sift flour or corn starch over the top.
Dot with butter.
Cover with a second crust, making openings for steam.
Bake
Bake at 350°F (175°C) for about 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Elderberries
- Provide the main filling and fruity flavor that the pie is built around.
- White sugar
- Sweetens the tart berries and helps draw out juice to form the filling.
- Flour or corn starch
- Thickens the juices so the filling sets rather than running out when sliced.
- Vinegar
- Adds acidity that brightens the berry flavor and balances the sweetness.
- Butter
- Adds richness and fat that enriches the filling and flavor.
The step that matters
Venting the top crust. Openings in the top crust let steam escape during baking. Without them, trapped steam can build pressure, make the crust bulge or split, and leave the filling wetter than intended.
