Yes Denmark is land of Danish pastry and a lot of other amazing baked goods but one of the most popular cakes, is mainly sold in gas stations and cheap supermarkets and it was never part of my Grandmother or mothers baking tradition.
The Lemon Halfmoon has been a long standing joke in the Danish work place. The cake symbolizes your lazy co-worker who just buy one of these for a birthday or Friday afternoon treat, while you of course always bring homemade cakes and treats.
Also the running joke is that police officers subsist on Lemon Halfmoons and they are even part of the political debate.
Baking one from scratch will endear you to everyone and perhaps even poke a bit of fun at the cheapskate who buy cake for the office at a gas station. —Andreadoria56
