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

Arrowroot
Thickens the water into a clear, glossy jelly as it heats and sets.
White sugar
Sweetens the jelly and adds body to its smooth texture.
Lemon juice
Adds acidity that brightens the flavour of the mild jelly.

The step that matters

Stir until clear, boiling steadily. Arrowroot must reach a steady boil to fully thicken and turn clear. Undercooked starch stays cloudy and runny and may not set properly when cooled.
