Dillisk or Dulse is a sea vegetable that grows in the intertidal zone, the region of shoreline found between high and low tides. It is found attached to rocks by means of a holdfast, it grows between 25 and 45 cm in length and is characterised by a red or purple translucent fronds. Dillisk grows and is harvested by hand during the spring and summer months, and then cured in open fields by the wind and sun after spreading thinly on netting. Frequently turned, the dillisk is ready for consumption when the leaves are covered with sea salt. In this state it has a shelf life of several years.
