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

What each ingredient does

Gelatine
Sets the liquid into a firm, sliceable jelly as it cools.
Lemons
Add bright acidity and fragrant citrus aroma from the rind and juice.
Eggs
Help the milky mixture set into a custard with a tender structure.
Milk
Adds richness and a soft, creamy texture to the set dessert.
Sugar
Adds sweetness and balances the tartness of the lemons.

The step that matters

Dissolve the gelatine fully before setting. Gelatine only sets properly when it is completely dissolved. Straining the mixture removes undissolved bits, and not cooking it keeps the gelatine's setting strength and a clear texture.

Swap the lemon

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

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

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