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
Separate the skins and pulp of the grapes.
Cook the pulp until soft.
In a bowl, mix the skins with sugar, flour, butter, and egg yolk.
Strain the cooked pulp and add it to the mixture.
Bake and top
Pour the filling into a pie crust and bake at 350°F (175°C) until set.
Beat the egg white and mix in 1 tablespoon of sugar.
Spread the meringue on top of the pie.
Brown the meringue.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grapes
- Provide the main fruit flavor and the juicy filling base.
- Egg yolk
- Helps bind and thicken the filling as it sets in the oven.
- Egg white
- Whipped into the meringue, giving the topping lightness and structure.
- Flour
- Thickens the filling so it sets rather than running out when cut.
- Sugar
- Sweetens the filling and helps stabilize the beaten egg white meringue.
The step that matters
Beat the egg white and sugar into meringue. Egg white needs to be beaten until it holds stiff peaks before the sugar is mixed in fully; underbeaten whites weep and deflate, while the sugar helps stabilize the foam.
Swap the grape
How well each one fits the dish's main ingredients (sugar, flour, butter, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Grapethe original
Fit is the average pairing score against sugar, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
