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

What each ingredient does

Gelatin
Forms the gel structure that sets the jelly firm as it cools.
Sugar
Adds sweetness and helps balance the sharpness of the lemon juice.
Lemons
Provide acidity and bright lemon flavour through their juice.

The step that matters

Dissolving the gelatin in the water. Gelatin must fully dissolve before the sugar and juice are added, otherwise it cannot set evenly and the jelly may come out grainy or weak.

Swap the lemon

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

  1. Vanillafits better
  2. Raisinfits better
  3. Figfits better
  4. Lemonthe original

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