4. Oliebollen, Netherlands
In the Netherlands, fried oil balls, or oliebollen, are sold by street carts and are traditionally consumed on New Year's Eve and at special celebratory fairs. They are doughnut-like dumplings, made by dropping a scoop of dough spiked with currants or raisins into a deep fryer and then dusted with powdered sugar.
In Amsterdam, be on the lookout for Oliebollenkraams, little temporary shacks or trailers on the street selling packets of hot fried oliebollen.
