Smørrebrød with Smoked Mackerel, Horseradish Mousse and Apple Salad
Smørrebrød with smoked mackerel, horseradish mousse and apple salad © kvalifood.com
Smoked mackerel is a widely available Danish classic, accessible year-round. The mackerel has a rich, bold flavour that can handle strong accompaniments, and horseradish is the traditional foil — the sharp root cuts through the oiliness of the fish. Here the horseradish is whipped into a light mousse, airier than the usual crème fraîche version. The apple salad with radishes and celery gives a crisp, sharp contrast that keeps the dish fresh. It is an everyday smørrebrød that is neither expensive nor complicated, but tastes of something when you put a bit of effort into the sides.
