There are a lot of wannabe doughnuts. And we're not just talking about the powdery five-packs of minidoughnuts you get at the gas station. No, there are poseurs throughout the pastry world—eclairs, bismarks, Burger King's new doughnut holes—just as there are also legitimate regional variations, such as the pączki (the Lenten batches at Bennison's should be your new annual tradition), berliner and bombolone.

This is not a scientific survey, merely my opinion. I'm not saying an eclair isn't delicious. It simply is not a doughnut.
