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

What each ingredient does

Gelatin
Sets the liquid into a firm, spreadable frosting that holds its cut shape.
Confectioners' sugar
Provides sweetness and bulk, thickening the frosting as it is beaten in.
Orange juice or water
Dissolves the gelatin and adds moisture to the frosting.

The step that matters

Dissolving the gelatin fully in hot liquid. Gelatin must be completely dissolved before the sugar is added, because undissolved granules won't set evenly and can leave a grainy, lumpy frosting.

Swap the lemon

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

  1. Vanillafits better
  2. Lemonthe original
  3. Mangofits about as well
  4. Figfits about as well

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