Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

All-purpose flour
Forms the structure of the crust that holds the filling.
Butter
Adds richness and tenderness to the crust and helps it flake when kept cold.
Prunes
Form the main filling and contribute sweetness and soft texture as they cook.
Sugar
Sweetens the prune filling and helps it thicken as it cooks.
Fruit juice
Adds moisture and fruity flavor to the filling as the prunes soften.
Chocolate
Adds deep, rich flavor to the prune filling.

The step that matters

Chilling the folded crust. Cold butter stays in solid pieces, and as it melts in the oven it creates steam pockets that make the crust flaky. Refrigerating firms the dough so it holds its shape and does not become greasy or tough.
