There is a curious subculture on YouTube of exploring and, sometimes at great personal risk, taste-testing military rations, sometimes from wars fought long before the tester/taster was born. Big Clive was motivated to contribute to this genre, and posted this taste test of one of the last MREs (Meals, Ready-to-Eat) prepared by the Scottish Army before it was assimilated into the British armed forces. All of the major food groups a proper Scotsman should require are provided: sugar, alcohol, carbohydrates, nicotine, and plutonium.
I guess they haven’t figured out how to make haggis last until the “best before” date. Maybe the plutonium would help, but maybe not. There is one naughty word in the video.
