Organic Sea Lettuce Porto-Muiños: the sea vegetable for signature cuisine
Organic dried sea lettuce (Ulva spp.) by Porto-Muiños is a hand-harvested Galician seaweed with an intense marine flavour and a subtle smoky note. Supplied in a practical 25 g pouch, it is certified organic (ES-ECO-022-GA, CRAEGA) and vegan, shelf-stable at room temperature for about three years. With 35 g of fibre and 29 g of protein per 100 g and a remarkable iodine content, it is the clean-label ingredient professional kitchens use to bring the sea onto the plate.
What sea lettuce is
Sea lettuce belongs to the genus Ulva, a green seaweed that grows along rocky Atlantic shores. Long part of coastal diets, it has become a staple of contemporary gastronomy as a "sea vegetable": dried, it concentrates minerals and umami while staying easy to store and portion. Once rehydrated it returns to bright green translucent sheets with a tender, slightly cartilaginous bite.
Galician origin
This sea lettuce is hand-harvested in its natural habitat on the coast of Galicia, between the Bay of Biscay and the Atlantic waters shared with northern Portugal. Harvesting by hand protects the marine bed and selects only the best fronds, which are then carefully dried to lock in colour, aroma and nutrients.
The producer: Porto-Muiños
Porto-Muiños S.L. is a family business founded in 1998 in Cerceda (A Coruña) by Antonio Muiños and Rosa Mirás. Pioneers of "sea vegetables" in Spain, they turned a then-unknown product into a gastronomic reference, becoming a historic supplier to Ferran Adrià's elBulli and to many leading restaurants around the world. Decades of research and sustainable harvesting make Porto-Muiños a benchmark for edible seaweed.
Sensory profile
Dried, the fronds are a dark green sheet with a fine, cartilaginous texture; on the palate the flavour is clearly marine, reminiscent of shellfish, with a light smoky finish. Rehydration revives a delicate brininess that recalls the sea breeze, without the heaviness of salt.
