Frozen custard is very popular throughout Wisconsin, as the ubiquitous Culver's chain demonstrates. (BTW, Culver's is the originator of the famous ButterBurger, a source of pride in the state known as "America's Dairyland.")
It would be hard to drive 15 miles in any direction in Wisconsin without seeing a Culver's. But Kopp's has only three locations, each one is in metro Milwaukee. And any foodie from Milwaukee is likely to insist that an out-of-towner make at least one trip to a Kopp's, especially for its frozen custard.
There were other flavors that sounded interesting — Pecan Praline Pumpkin Pie and Strawberry De Leche, to name a few — but the idea of Maple Syrup and Pancakes frozen custard made me very curious so I just had to try it.
My verdict? It was strange, but sort of good. There were small strips of pancake dough within the custard.
Kopp's normal-sized hamburger is huge. Don't order the larger burger unless you have a voracious appetite.
One thing I like about both Culver's and Kopp's is that when you order a burger, one of your options is to order it served with raw onions or fried onions.
