Tesco seaweed spaghetti

Tesco has become the first British supermarket to stock fresh seaweed as it looks to capitalise on the latest ‘superfood’ trend.

The retailer is selling 80g pouches of fresh himanthalia elongata, or ‘sea spaghetti’, supplied by The Cornish Seaweed Company, in 71 stores.

Promoted by chefs Nathan Outlaw and Raymond Blanc, seaweed has been tipped as a key foodie trend. Dried products have already enjoyed success in retail.

The Cornish Seaweed Company - founded in 2012 by Tim van Berkel and Caro Warwick-Evans - harvests the sea spaghetti by hand from Cornwall’s Lizard peninsula. It is rich in immune-boosting polysaccharides such as laminarin.
