From this time of the year untill the end of the year everywhere in the Netherlands "oliebollen" are sold.
This is a variety of dumpling made by two spoons to scoop a certain amount of sough and dropping it into a deep fryer filled with hot oil. See http://en.wikipedia.org/wiki/Oliebol
Another dutch speciallity is "drop", the black ones in the baskets. Most foreigners don't like them but the Dutch love the taste and can't without them. You see how much variations there are, sweet, salt or dubble salt. See http://en.wikipedia.org/wiki/Liquorice_(confectionery)
