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

What each ingredient does

Irish moss
A seaweed that contains gelling compounds, so it thickens the milk and sets it as it cools.
Milk
Forms the body of the dessert, providing moisture, creaminess and the base for setting.
Sugar
Adds sweetness and balances the mild flavour of the milk and moss.

The step that matters

Soaking and draining the moss. Irish moss must be soaked long enough and rinsed to remove sand and grit. Draining off excess water keeps the milk mixture at the right strength so the dessert sets properly rather than thin or gritty.
