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.
Prepare the filling
Preheat the oven to 350°F (175°C).
Beat the egg and sugar together in a bowl.
Add the grapes, flour, and a little butter to the mixture.
Assemble and bake
Pour the filling into a pie crust and cover with the second crust.
Bake until golden brown.

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
- Egg
- Binds the filling and helps it set as it bakes.
- Sugar
- Sweetens the filling and adds moisture to the mixture.
- Grapes
- Provide the fruit filling and its juice, which adds moisture and flavour.
- Flour
- Thickens the juices so the filling sets rather than running out.
- Butter
- Adds fat for richness and flavour in the filling.
The step that matters
Add the flour to the filling. Flour thickens the juices released by the grapes as they bake. Too little, or mixing it poorly, can leave a runny filling that soaks the crust.
Swap the grape
How well each one fits the dish's main ingredients (egg, sugar, flour, butter):
- Raisinfits better
- Vanillafits better
- Figfits better
- Grapethe original
Fit is the average pairing score against egg, sugar, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
