A pale set milk-pudding made by simmering dried Irish moss (carrageen seaweed) in milk with sugar and vanilla — the seaweed releases its natural gels into the milk, which then sets like a soft panna cotta when chilled. Topped with cream and whiskey or stewed rhubarb. The west-coast Irish dessert and pre-modern folk-medicine remedy for chest colds.
Carrageen moss (Irish 'carraigín', meaning 'little rock') is a red seaweed that grows on rocky shores all around the Irish coast, and is especially associated with the Atlantic west — counties such as Clare, Mayo, and Donegal. Coastal families harvested it at low tide, dried and sun-bleached it on stone walls or grass, and used it both as a folk remedy (simmered in water with lemon or a little whiskey, its mucilage thought to ease coughs and chest colds) and as a setting agent for milk puddings. The pudding became a common Sunday dessert in fishing villages, where eggs and cream were scarce but milk and seaweed were essentially free; during the 19th-century Great Famine the seaweed was also simmered into sweetened, spiced milk as a fortifying drink. Carrageenan was later extracted from the moss as an industrial food stabiliser, but the home-pudding tradition survives.
Spoon dips into a soft trembling milk-set that gives way completely — softer than panna cotta, holds shape only briefly. Flavor is gentle milk-and-vanilla with a barely-there mineral whisper from the sea. The optional whiskey lifts the cream into something almost adult. Stewed rhubarb is the tartness that makes the dessert work.
Dried carrageen moss is soaked until it swells, then simmered in milk for around 15 minutes. As it heats, the seaweed releases its natural carrageenan, which forms a weak gel network that lightly sets the milk. The mixture is strained through a fine sieve (pressing the jelly through; undissolved moss tastes of seaweed), sweetened, and flavoured with vanilla — often enriched by whisking in an egg yolk to a custard, with the white sometimes whipped to peaks and folded back in for a frothy top. Chilled in a mould for several hours, it sets to a soft, light, barely-wobbling pudding. The set comes entirely from the seaweed's own carrageenan, not added gelatin — and unlike gelatin, carrageenan gels are heat-stable, though at this low concentration the set is delicate.
Variations
Honey-sweetened version (skipping sugar) was the older Donegal style. Goat-milk version exists in the western islands. Cocoa carrageen pudding is the 20th-century Cork addition. Modern fine-dining versions strain three times for an ultra-smooth panna-cotta-like result.

How it's made
7 steps · 15 min active + 3 hours 45 min waiting
- 116 min
Soak 8-10 g dried carrageen moss in cold water 15 minutes. Drain and rinse — picks remove sand and shell bits.
- 24 min
Combine soaked moss with 600 ml whole milk in a saucepan. Bring to bare simmer.
- 318 min
Hold at the gentlest simmer 15-20 min — the moss will swell and start dissolving, milk will visibly thicken.
Watch outBring the milk only to a bare tremble, never a rolling boil — the carrageen sets a delicate gel and hard heat breaks it.
- 43 min
Strain through a sieve into a bowl, pressing the moss against the sieve to extract maximum gel. Discard moss pulp.
Watch outHold that gentle simmer until the moss swells and the milk visibly thickens and coats a spoon — that's the gel releasing.
- 52 min
Whisk in 60 g sugar, 1 tsp vanilla, pinch of salt. Optional: 2 tbsp whiskey.
- 6200 min
Pour into 6 small bowls or one big bowl. Refrigerate 3-4 hours until softly set (like firm yogurt).
Watch outPress the jelly firmly through the sieve to squeeze out every bit of gel, but leave the pulp behind — undissolved moss tastes of the sea.
- 72 min
Serve with a spoon of cream poured over and stewed rhubarb, raspberries, or a whiskey drizzle.
