@tsarstepan,
Creme eggs have been here for a very long time. I remember them from when I was a kid. At one point they were available all year round but they found they sold more if they limited sales to the run up to Easter.
After Easter they’re not in the shops. Not until just before Christmas, and I mean just before, 20th, 21st December and completely unannounced. They just quietly appear. They don’t get advertised until February.
I don’t know, but spotting a creme egg on Christmas Eve gives me a warm feeling. It shines a light beyond the depressing post Christmas time of darkness, and the nights are a fair bit longer over here in Winter.
I like to put one in the children’s stockings.
As an aside I read somewhere that people’s taste for chocolate is based on what they ate when they were kids. Cadbury’s has always been my favourite chocolate, I really like creme eggs, but flakes are divine, they’re the best. At the same time I don’t like Hershey’s chocolate, and I’m sure a lot of people feel differently in America.
