One of the weird things I had to get used to when we moved to Seattle was the shape of the butter. No, really.
Butter in Minnesota is long and slender. Butter in Seattle is usually sold in a form called "the Western stubby" (yes, that sounds dirty to me, too) and is short and fat. People in Minnesota look at me with disbelief when I describe it and people in Seattle don't seem to know any other way.
Apparently now Minnesota's own Land o'Lakes is giving in and making butter in the Western stubby format, but will only sell it in Western states.
