Laver, purple laver, redware or sea tangle is one of the most commonly eaten seaweeds. Sheets of dried laver look somewhat like purple cellophane. Called Nori by the Japanese, it is also popular in Wales, where it is used to make 'laverbread'. Welsh laverbread is boiled laver mixed with oatmeal and deep fried. Laverbread is used to thicken soups and in seafood stuffings.
