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

What each ingredient does

Irish moss
Seaweed whose natural gelling compounds thicken the liquid and make it set as it cools.
Milk
Adds creaminess and richness, giving the set pudding a smoother, softer body.
Sugar
Adds sweetness to balance the mild, slightly sea-like flavor of the moss.

The step that matters

Boil for the full 5-7 minutes. Heat is needed to dissolve the moss's gelling compounds into the liquid. If the mixture is not boiled long enough, the compounds stay partly undissolved and the pudding may not set firmly as it cools.
