Part of a full breakfast. Laverbread is known as either 'Welshman’s caviar', a luxurious seaweed dish that’s often mixed with cockles, or as that weird, slimy green stuff nudged grimly to the side of the plate when eating a full Welsh breakfast. The great 'love it/hate it' item on this list, laverbread encourages great passions either way, especially from diners expecting ‘bread’ of some description to play a part. Much like oysters, laverbread offers an intense taste of the sea, and healthy-eating-types should note that it contains blood-purifying levels of iron.
