The Victorians grew pineapples in special pineapple pits, where the required heat was provided by a surrounding layer of fermenting manure. The Lost Gardens at Heligan in Cornwall have produced ripe pineapples using the Victorian method in their restored pineapple pit. Due to the huge amount of labour involved, these pineapples cost between £600 and £1,000 each to produce in 1997.
A Bit Of Trivia
Workers who cut up pineapples eventually have no fingerprints, this being due to the action of the proteolytic enzyme, bromelain, dissolving them. This trick is well-referenced by authors of the crime novel world.
