Nanaimo Bar
Well, it has to start with 'N' of course. It has to be something sweet. The only suggestion here that works so far is "Nougat". But, as a Canuck, and a fan of the Christmas favourite, I think "Nanaimo Bar" is the winner. It's minor downsides are that its hard to spell for some, and it may not be well know outside of Canada. Whot??? There's no nanaimo bar icon???
