Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Corn starch
Thickens the boiling water into a firm gel as the starch swells and sets when cooled.
Sugar
Adds sweetness and balances the mild, starchy flavour of the jelly.

The step that matters

Boil for five minutes, stirring continuously. Corn starch thickens only once its granules have swelled fully in boiling water. Stopping the stirring lets the starch settle and scorch on the bottom of the pan, and undercooked starch leaves the jelly thin and gritty.

Swap the lemon

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

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

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