Danes are crazy about their hot dogs. On nearly every Copenhagen corner, a pølsevogn, or hot dog wagon, offers more than a dozen varieties. The knockout ristet hot dog, accented with sweet spices, gets tucked in a bun loaded with pickles, raw and crispy fried onions, and a delectable remoulade; the medister is a sausage spiced with cloves and allspice; and the fransk, or French hot dog, makes ingenious use of a baguette-like roll, the bread hollowed out and used as an edible sleeve for the footlong frank. They always beckon as we stroll through the city, even if we've just eaten one a few blocks before.
