Stargazy pie (sometimes called starrey gazey pie or other variants) is a Cornish dish made of baked pilchards, 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. This allows the oils released during cooking to flow back into the pie.Text from Wikipedia. Image from The Telegraph, which has a gallery of ten British foods with strange names.
The dish is traditionally held to of [sic!] 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 during a very stormy winter. According to the modern festival, which is combined with the Mousehole village illuminations, the entire catch was baked into a huge stargazy pie, encompassing seven types of fish and saving the village from starvation. There is evidence that the festival dates back even further, to pre-Christian times.
