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

What each ingredient does

Prunes
Provide the main fruit flavour and body, softened and rubbed into the jelly.
Gelatine
Sets the liquid into a firm, wobbly jelly as it cools.
Loaf sugar
Adds sweetness and balances the tartness of the prunes.

The step that matters

Dissolve the gelatine fully before adding it. Gelatine must be completely dissolved in warm liquid and mixed evenly; undissolved granules leave gritty specks and weak patches, so the jelly may not set uniformly.

Swap the cinnamon

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

  1. Nutmegfits about as well
  2. Cinnamonthe original
  3. Gingerfits less well
  4. Peppermintfits less well

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