Breakfast pastries are the sweetest (European) way to start the day!
When I moved back to Europe, after a long period in the US, a friend of mine welcomed me at the airport holding a bag of fragrant croissants with almonds and pain au chocolat.
I missed their butter smell so much!
Useless to say that they didn't last long...
In Luxembourg, do not miss the ones from Oberweis, one of the most popular pastry shops in the Grand Duchy and supplier of the Court!
