Do nuts
A few years ago we had a 'Dunkin' Donuts' at Utrecht Central Station. Besides delicious donuts they sold munchkins too. I really miss them... Munchkins are spherical pieces of dough, originally made from the middle of a ring donut.
Did you know the origin of donuts might come from the Dutch doughnuts ('oliebollen') which we still eat on New Year's Eve?
