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

What each ingredient does

Irish moss
Seaweed that releases gelling compounds as it simmers, setting the liquid into a jelly.
Water
Extracts the moss's gelling compounds and forms the body of the jelly.
Loaf sugar
Adds sweetness to balance the jelly's flavor.

The step that matters

Boil the mixture until it thickens to a jelly consistency. Irish moss sets only after its gelling compounds have been extracted by simmering. Boiling too briefly leaves the liquid runny, while overcooking can make the jelly stiff and cloudy.
