Upon realising his predicament, Mr McCabe initially thought he “was OK because I could kick the safety button from inside”, but “this time it was frozen solid”.
Stuck in temperatures capable of killing a human in about an hour, the father-of-four searched frantically for an improvised tool to batter the button.
With the beef too slippery and the lamb too big, he happened on the “best thing” – the black pudding, made by the Queen’s butcher HM Sheridan of Ballater, Aberdeenshire, who Mr McCabe has been buying the pudding from for more than 20 years.
He said: “It was the right shape. I used it like the police use battering rams to break door locks in. It was solid, pointed and I could get plenty of weight behind it.
“I’m lucky really. We sell about two or three each week and that was the last one in there.”
