13Professor Michael O'Kelly took such experimentation even further while excavating a fulacht fiadh at Ballyvourney in Co. Cork. Using a 4.5 kg (10 lb) leg of mutton, he tied it inside a bundle of straw to keep out the muddy grit from the water. He then lowered the bundle of meat into the boiling water. (O'Kelly, Michael.
