The roast beef sandwich is yet another classic piece of smørrebrød. Generous layers of roast beef are stacked with remoulade, capers, sweet dill pickles, fried onions, salt and pepper. It comes with a variety of options, such as different smears (duck fat, butter, roasted garlic or mustard like this one). Typically it also has a nice little dash of shredded horseraddish, but I couldn’t find any on the day I made this.
In Denmark, smoked mackerel was formerly a delicacy reserved for special occasions such as family Christmas luncheons, or fancy dinner parties. Danish smoked mackerel typically comes from Bornholm, which is famous for its many smokehouses. Although made with smoked mackerel, this sandwich would work well with other smoked fish e.g. smoked salmon.
