We say: The more unusual, the better. Normally, in Germany and other German-speaking countries, berliners are the typical piece of baked goods for carnival. But they are offered all year round – sometimes in the shrillest colours.
By the way, there is a similarly shrill legend that explains the origin of berliners: During an argument, a woman is said to have thrown a lump of dough at her husband, but it landed in a pot of hot fat and – ta-taa – the berliner was born. Perhaps a nice anecdote to tell customers while bagging. And to go with it? Why not give your berliners an extravagant topping or serve them standing upright with a topping of cream and fruit? The sky is the limit!
