Medieval England was unexpectedly full of coconuts. Following ancient practices, the English used coconut milk, meat, and oil medicinally. By the thirteenth century English imported coconuts from the Venetians and once the medicine was extracted, craftsmen transformed the leftover coconut shells into goblets harnessed in precious metals modelled after traditional mazers.
