The bright red colour of the classic røde pølse is pure dye; a popular story says butchers once dyed older sausages red to sell them off cheaply, though the tale is hard to verify.
Served from freestanding hot dog carts called pølsevogne found on street corners across Denmark, a Danish hot dog usually comes piled with a mix of raw and crispy fried onions, remoulade, mustard, ketchup, and pickles.
Why it's made this way: The first pølsevogne rolled onto Copenhagen's streets in the early 1920s, and the cart format persisted because it let vendors serve hot food quickly from almost any street corner.
