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 gel as it boils and then cools.
Sugar
Adds sweetness and balances the mild starch flavor.

The step that matters

Boil for 5 minutes, stirring continuously. Starch granules only swell and thicken fully once they reach a boil. Constant stirring prevents lumps and scorching at the bottom of the pot, giving a smooth, evenly set jelly.

Swap the lemon

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

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

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