Four large barrel-shaped lumps of the foodstuff have appeared on the Angus coastline after storms on the east coast, according to staff at the nearby St Cyrus nature reserve.
According to BBC News, the lard is thought to have come from a boat that was bombed during the war, and was originally contained in wooden barrels.
St Cyrus reserve manager Therese Alampo explained: "The depth of the swell during the storms we had over the holidays must have broke apart the shipwreck some more and caused the lard to escape."
However, local resident Angus McHardy has said that it is not the first time that lard has appeared on shore in the area.
McHardy revealed: "Some barrels were complete and others were just lumps. People collected it. My grandma boiled it up to get the sand out. It was great because we couldn't get any fat during the war.
"After a storm in the late '60s or '70s, the lard came up on shore again."
