On the Sligo coast tradition had it that one dangerous sea rock, and the dillisk that grows on it, held the cure to life threatening worms. In this programme the country’s leading seaweed expert, Dr. Prannie Rhatigan (above) confirms this is no piseog or superstition. We recreate the dash to the Worm rock, harvest some dillisk, take it back to Prannie’s kitchen and make some dillisk crisps, a big favourite of ten-year-old Kate Waters.
