Fruitcake is known to stay fresh for an inordinate amount of time.

But Antarctic conservators say they recently came upon a specimen that tests the limits of the treat: a 106-year-old cake, found in one of Antarctica's first buildings.

This particular cake is believed to have been brought over in 1910 during the Terra Nova expedition of Robert Falcon Scott. According to the Antarctic Heritage Trust, "it has been documented that Scott took this particular brand of cake with him at that time."

The Huntley & Palmers fruitcake was wrapped in paper and housed in a tin-plated iron alloy tin, which is showing signs of deterioration. However, the cake itself is "well-preserved," the conservators say.

"There was a very, very slight rancid butter smell to it, but other than that, the cake looked and smelled edible!" the Trust's Programme Manager-Artefacts Lizzie Meek said in a statement. "There is no doubt that the extreme cold in Antarctica has assisted its preservation."

The century-old dessert was found with nearly 1,500 other artifacts from two huts at Cape Adare.

According to the Trust, the first buildings on the continent "were built by Norwegian Carsten Borchgrevink's expedition in 1899 and later used by Captain Scott's party in 1911." Meek says the team members were finishing up their work collecting objects when they were surprised to find the old dessert.

She adds that even present day explorers love a good fruitcake: "It's an ideal high-energy food for Antarctic conditions, and is still a favorite item on modern day trips to the ice."

The cake's sheer density probably helps. As NPR's Maria Godoy has reported, people doing outdoor work in the Antarctic need about 5,000 calories a day — and more like 6,500 if you're involved in manhauling, which is "pulling sleds across the ice and snow with their bodies."

Maria writes that there's one clear lesson that Antarctic explorers have learned over the years: "When life is stripped down to man versus the most brutal elements, bring plenty of snacks."

This is something Scott's team knew — in fact, Maria says that "his party conducted a study that suggested a high-carb, high-fat diet to be optimal for the harsh climes."

But tragically, explorers on Antarctic expeditions were often hungry. Scott himself starved to death while on the return journey from the South Pole.
