Lemon and sugar 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

Bermuda arrowroot
Thickens the liquid as its starch swells in boiling water, turning it clear and gel-like when cooled.
White sugar
Adds sweetness and helps give the jelly a smooth, pleasant body.
Lemon juice
Adds acidity that brightens the flavour and balances the sweetness.

The step that matters

Stir until clear while boiling steadily. Arrowroot starch must reach a full boil to thicken fully and turn clear. Stopping early leaves the jelly cloudy, lumpy or too loose to set.
