My favorite donut is the Bismarck. They are sold in grocery stores in Northern Iowa. I thought I would post a photo because, believe it or not, they don't sell these everywhere. You might find an imitation but it won't be called a Bismarck. The one I ate today had yellow icing piped on it, which is not typical. Usually you just have the white frosting.
A Bismarck is actually based on a donut called the
Berliner. Berliners are traditionally eaten to celebrate on
New Year's Eve (
Silvester) as well as the
carnival holidays (
Shrove Tuesday). A common
practical joke is to secretly fill some Berliners with
mustard instead of jam and serve them together with regular Berliners without telling anyone.
