Taste buds in my native Minnesota certainly have changed over the years.  This year's new Fair food offerings include some Japanese Influences. I think I'll pass on the Spam sushi but the Taiyaki influenced ice cream cone is cute. 

The Minnesota Corn Dog made with a custom ground sausage that included apples, blueberries and wild rice does sound interesting.  So does the Sheep Dog, a lamb hot dog in a bun with garlic sautéed kale, raw fermented sauerkraut, quinoa and honey mustard drizzle.

Tradition still sells.  I understand there are still long lines for the Tom Thumb donuts and several Pronto Pup stands.  (The MN State Fair Pronto Pup batter is a special mixture of several flours with a texture more like pancake batter than corn bread.)  Both foods have been patt of the fair for over 65 years.
