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 ↓
Grape 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the filling
In a bowl, mix the egg, flour, sugar, and butter until well combined.
Add the cooked and seeded grapes to the mixture and stir gently.
Assemble and bake
Pour the filling into one pie crust and cover with the second crust.
Bake for 30-40 minutes or until the crust is golden brown.

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.

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
- Grapes
- Provide the fruit filling and its sweet, juicy flavor once cooked.
- Egg
- Helps bind the filling so it holds together when sliced.
- Flour
- Thickens the juices released by the grapes as the pie bakes.
- Sugar
- Adds sweetness and helps balance the tartness of the grapes.
- Butter
- Adds richness and fat, contributing to flavor and a tender texture.
The step that matters
Bake until the crust is golden brown. Baking long enough sets the thickened filling and fully cooks the crust. Underbaking leaves the filling runny and the bottom crust pale and doughy.
Swap the grape
How well each one fits the dish's main ingredients (egg, flour, sugar, butter):
- Raisinfits better
- Vanillafits better
- Figfits better
- Grapethe original
Fit is the average pairing score against egg, flour, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
