Hotdogs are Copenhagen’s street food. It was the first and the only one for many years. We have a nickname for a hotdog stand: “Restaurant Cold Feet”.
Growing up in the 1970s, having a hotdog was a treat. The sheer excitement of choosing between ketchup, mustard, rmoulade, or all together. Then the choice between raw or fried onions? And did you want it with or without pickled sliced cucumber? I always had fried onions, and the cucumbers were the absolute best for me. They made the hotdog perfect.
I remember mostly having homemade hotdogs at special occasions, and often at birthday parties. We would buy thin sausages at the butcher and bake the buns ourselves. It was good for parties and perfect with beer, and also great for dinner. When I made them for my kids, I would always serve them with a red cabbage salad. It is still a combination that works for me.
