Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn starch
- Thickens the liquid into a smooth, sliceable filling once it boils.
- Egg
- Adds richness and helps the filling set as it bakes.
- Butter
- Adds fat for a rich, tender texture and smooth mouthfeel.
- Sugar
- Sweetens the filling and balances the lemon's tartness.
- Lemon juice and rind
- Provides the tart, bright flavour and lemon aroma.
The step that matters
Wet the corn starch before stirring it in. Dry starch clumps in hot liquid, leaving lumps. Mixing it with cold water first lets the granules disperse evenly, and the filling only thickens fully once the mixture reaches a boil.
Swap the lemon
How well each one fits the dish's main ingredients (corn, sugar, egg, butter):
- Vanillafits better
- Coconutfits better
- Figfits about as well
- Lemonthe original
Fit is the average pairing score against corn, sugar, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
