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

What each ingredient does

Iceland moss
Its natural gelling compounds thicken the milk and let the pudding set firm.
Milk
Forms the liquid base and adds richness and a creamy body to the pudding.
Sugar
Adds sweetness and balances the mild, earthy flavour of the moss.
Lemon rind
Its aromatic oils add a bright citrus scent without adding liquid.

The step that matters

Simmer gently for one hour. Gentle heat draws the gelling compounds out of the moss while keeping the milk from scorching on the base of the pot. A hard boil can burn the milk, spoil the flavour, and make the set uneven.

Swap the lemon
