Assemble and serve

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

What each ingredient does

Prunes
Provide the main body, fruity flavor, and sweetness of the filling.
Flour
Starch that thickens the prune mixture as it cooks.
Sugar
Adds sweetness and balances the tartness of the prunes.
Butter
Adds fat for richness and a smooth, silky texture.
Nutmeg
Adds a warm aromatic spice note to the filling.

The step that matters

Cook the mixture until it thickens. Flour starch only thickens fully when heated, so cooking until thick gives a stable filling and removes the raw flour taste. Undercooked filling stays loose and may slice poorly.

Swap the nutmeg

How well each one fits the dish's main ingredients (sugar, flour, butter, cream):

  1. Nutmegthe original
  2. Cinnamonfits about as well
  3. Jalapenofits less well
  4. Capersfits less well

Fit is the average pairing score against sugar, flour, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
