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

What each ingredient does

Guavas
Provide the fruit flavour and the natural pectin that helps the jelly set.
Sugar
Sweetens the jelly and helps it set by binding water, firming its texture.
Lemon juice
Adds acidity that brightens flavour and helps pectin set the jelly.

The step that matters

Cooking to the desired consistency. Jelly sets as the mixture thickens and sugar and pectin reach the right balance. Cooking too little leaves it runny; cooking too long can make it stiff and dull in flavour.
