And so, here are my top 5 donuts:
5. Cake donut - with or without sprinkles
3. Old Fashioned
2. Bismarck - aka Boston Cream - aka Berliner. Although I believe technically these can be filled with a variety of things, it is the custard filled ones that I love. Incidentally, when John F Kennedy made his famous proclamation, "Ich bin ein Berliner" he was telling the good people of berlin that he was a donut. Sort of like if he had gone to Hamburg, Germany and declared, "Ich bin ein Hamburger." Kind of amusing, but they knew what he was talking about.
1. Apple fritter. The tastiest donut of them all. It is one of the greatest human achievements of our time. I rank it just below the wheel.
