I happen to be a doughnut epicure. I only care for plain doughnuts (God forbid, not "whole wheat"), deep fried in fat to a dark crunchy crust. If somebody insists on a dash of confectioner's sugar on top, that's OK but I'd be just as happy without it.
Cake doughnuts are revolting, like the ones at Bird Dog's favorite coffee joint or at the supermarket. You can feed them to kids and dogs, though, and they seem to thrive on them. Don't even talk about that Krispy Kreme gooey junk.
A real fried doughnut, and a cup of black coffee. Heaven. Then maybe a smoke to finish off the coffee. You do have to look around, though, to find places that make real doughnuts these days. Real doughnut-lovers know where they are.
