Stargazy pie Stargazy pie Stargazy pie (sometimes called starrey gazey pie, stargazey pie and other variants) is a Cornish dish made of baked pilchards (or sardines), along with eggs and potatoes, covered with a pastry crust. Although there are a few variations with different fish being used, the unique feature of stargazy pie is fish heads (and sometimes tails) protruding through the crust, so that they appear to be gazing skyward. The dish is traditionally held to have originated from the village of Mousehole in Cornwall and is traditionally eaten during the festival of Tom Bawcock's Eve to celebrate his heroic catch
Pie and mash eels were one of the few forms of fish that could survive in the heavily polluted River Thames and London's other rivers at that time. Supply was plentiful through the late 1800s, particularly from the Dutch fishing boats landing catches at Billingsgate Fish Market. Since 2010, as revealed in a joint study by the Zoological Society of London and the Environment Agency, the number of eels captured in research traps in the River Thames fell from 1,500 in 2005 to 50 in 2010, meaning most eels used in pie and mash shops are now from the Netherlands and Northern Ireland.
