Liz is right. Bird were put into a pre-baked pie crust. My medieval cookery book is full of spectacle recipes to amaze diners. How about a cockentrice? It's the front of a cooked chicken sewn to the hindpart of a cooked suckling pig, then endored with gold (saffron mixed with egg yolks and flour). I'd be amazed if this was served to me. Wouldn't you?
