Cadbury Oreo Snowy - 246g

In Britain, the run-up to Christmas is when the supermarket biscuit aisle quietly changes its clothes. The everyday names put on their winter versions, and the Cadbury purple turns up on more shelves than seems strictly necessary. This is one of those winter editions, and it is the kind people notice.

Most people looking for it in Canada are not after any old biscuit. They are after the one they remember from a UK Christmas, the packet that sat next to the tin of chocolates and the bowl of nuts nobody cracked. A taste of home at Christmas is usually a small thing. This is a small thing.

It comes as a 246g packet, which is a decent amount for a sofa full of family if somebody is strict about it. Keep it in a cool, dry cupboard and fold the packet shut between raids. It goes with a cup of tea, a film you have all seen before, and a stocking that needs something more interesting than socks.

Cadbury fans tend to build a little stash around it: a bar of Dairy Milk, a box of Fingers, a tin of Roses or Heroes for after dinner. The same people usually add a box of proper British tea to the basket while they are at it.
