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

What each ingredient does

Irish moss
Its natural gelling compounds thicken the milk and set it into a firm, sliceable blancmange.
New milk
Forms the liquid base that the moss thickens and sets, giving the dessert its body and creaminess.
Sugar
Sweetens the set dessert and balances the mild, milky flavor.

The step that matters

Simmering until the consistency of cream. Irish moss must be cooked long enough in the hot milk for its gelling compounds to dissolve and thicken the liquid. Too little heat or time leaves it thin and unable to set when cooled.
