Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Irish moss
- Seaweed that thickens the milk into a jelly as it simmers and cools.
- Fresh milk
- Forms the body of the jelly and gives it a creamy, mild flavor.
The step that matters
Boiling until the milk reduces to 1 pint. Irish moss sets the milk through its gelling compounds, which are released by simmering. Reducing too little leaves the jelly loose, while reducing too far makes it stiff and rubbery once cooled.
Swap the lemon
How well each one fits the dish's main ingredients (irish moss, milk, sugar):
- Vanillafits better
- Lemonthe original
- Peachfits about as well
- Coconutfits less well
Fit is the average pairing score against irish moss, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
