Porphyra umbilicalis, Bara lawr, the Welshman’s caviar, Laver bread. A dark green – or is it red? – or pink or deep brown? seaweed that is simultaneously the crowning joy and sharpest point of division of all Welsh foods.

Crowning joy, because this is a true delicacy, with a deep umami flavour and a rich, smooth texture that fills your mouth.

Sharp point of division, because, like Marmite, this is a love-it-or-hate-it foodstuff, shunned and adored in equal measure even within the same family.
