The Bola de Berlim (Berlin Ball) may look like an ordinary doughnut, but it is uniquely Portuguese. The recipe is based on that of a German doughnut (Berliner Pfannkuchen), which was reportedly brought over to Portugal by Jewish refugees during the Second World War. However, it has been given a Portuguese identity by adding a filling of creme pasteleiro (a type of egg custard similar to crème pâtissière) instead of jam. As well as the traditional egg custard creme, there are also other flavours on offer, such as chocolate or strawberry, and there is even an option to have a Bola de Berlim without any filling (sem creme). Who would have thought that ordering a doughnut could be so complicated! As with all sweet snacks in Portugal it is delicious but very calorific, which makes it ironic that it is also one of the most popular snacks sold on Portuguese beaches!
