Why it works: Irish moss and lemon work together. They rank in the top 10% of all ingredient pairs, and cooks put them together in 61 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Blanc Mange
Ingredients
Directions
Prepare the milk
Wash the Irish moss thoroughly and place it in a pail.
Pour the milk over the moss.
Cover the pail and set it in a kettle of boiling water.
Let it stand until the moss thickens the milk, then strain through a fine sieve.
Flavor and mold
Add sugar and lemon flavoring to taste.
Wet the molds in cold water and pour in the blanc mange mixture.
Set the molds in a cool place until firm.
Turn out and serve
Loosen the edges from the molds and turn out onto a china or glass plate.
Serve with sugar and cream.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Irish moss
- Thickens the milk as it stands, setting it into a gel-like texture.
- Milk
- Forms the liquid base that the moss thickens into the set dessert.
- Sugar
- Adds sweetness and balances the flavor of the milk.
The step that matters
Letting the moss thicken the milk. Irish moss is a seaweed whose natural gelling compounds release slowly in warm liquid. Holding the milk warm long enough lets it thicken fully; the mixture must then be fully firm before unmolding, or it will slump.

- Peachabout as good a flavor fit
Fit is the average pairing score against milk, sugar, irish moss. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
