In high school, I went to Holland on a school-sponsored exchange program. One thing I discovered was the delicious stroopwafel, a treat made from two crisp wafers held together by spiced caramel.
Stroopwafels are traditionally placed over a hot mug of coffee or tea. Not only do they act as mug snugglers, but the steam from the beverage softens the wafer and the caramel inside. In other words, they are perfect cold weather treats.
I found these at Cost Plus World Market, and recommend the brand (each box contained 8 wafers and cost $4). People in larger cities should also check in the international sections of their grocery stores or at local bakeries. You can buy stroopwafels online at Amazon 
Have you eaten stroopwafels? If so, what did you think?
