Cottleston Pie was written by A.A. Milne in the 1926 classic “Winnie the Pooh”. In the chapter entitled “In Which Eeyore Has a Birthday and Gets Two Presents”. Eeyore is complaining in a roundabout way about the absence of his birthday celebration, but Pooh can’t figure out what he is talking about.
“Pooh sat down on a large stone, and tried to think this out. It sounded to him like a riddle, and he was never much good at riddles, being a Bear of Very Little Brain. So he sang Cottleston Pie instead:” - A.A.Milne
Since then the poem has been attributed with various philosophic meanings, and some chefs were inspired by the poem to create real recipes for “Cottleston Pie”. But for Pooh it was merely a way to cope with things he didn’t understand.
