Blackbird

From the 1549 Italian cookbook Epulario or The Italian Banquet by Giovanni de Roselli, translated into English in 1598:
TO MAKE PIE THAT THE BIRDS MAY BE ALIVE IN THEM, AND FLIE OUT WHEN IT IS CUT UP

Make the coffin of a great Pie or pasty. in the bottome whereof make a hole as big as your fist, or bigger if you will. let the sides of the coffin be some what higher then ordinary Pie, which dome. put is full of flower and bake it, and being baked, open the hole in the bottome and take out the flower [flour]. then having a Pie of the bignesse of the hole in the bottome of the coffin aforesaid. you shal put it into the coffin, withall put into the said coffin round about the aforesaid pie as many small live birds as the empty coffin will hold besides the pie aforesaid. And this is to be done at such time as you send the Pie to the table, and set before the guests: where uncovering or cutting up the lid of the great Pie, all the Birds will flie out. which is to the delight and pleasure shew to the company and because they shall not bee altogether mocked, you shall cut open the small pie and in this sort tart you may make many others, the like you may do with a Tart.
