Check out this sugary summary from the Food Network. And if you don't go get a doughnut afterwards, congratulations on your will power!
Minnesota's entry is from Mojo Monkey Donuts, a great spot in St. Paul. Here's what Food Network says about Mojo Monkey:
The exotic flavors of this mango-glazed doughnut are one example of owner Lisa Clark’s mission to make amazing raised doughnuts (assisted by her pastry-enthused children). Mojo Monkey Donuts’ signature yeast dough (crafted with locally brewed beer, yams and parsnips) is made into a ring, then topped with organic mango glaze and unsweetened coconut for a tropically inspired treat.
