Smørrebrød with Mackerel in Tomato, Horseradish Cream and Rye Crisps
Mackerel in Tomato with Horseradish Cream and Rye Crisps © kvalifood.com
Canned mackerel in tomato is one of Denmark’s most popular toppings — a tin of mackerel in tomato in the fridge is practically a cultural marker. It is cheap, filling and tastes of childhood for many Danes. Here it is upgraded from kitchen-counter food to proper smørrebrød with homemade horseradish cream, which gives a sharp bite against the sweetness of the tomato, and crispy rye crisps that add crunch. Red onion rings bring freshness and sharpness. It is still everyday food at heart, but with the kind of accompaniments that show you have taken the time to do it properly.

Yields 4 servings
Horseradish cream
- 1 dl crème fraîche 38%
- 2 tbsp freshly grated horseradish
- 1 tsp lemon juice

Rye crisps
Brush the rye bread strips with olive oil and sprinkle with flake salt. Bake in the oven at 355°F (180°C) for about 10 minutes until crispy. Keep an eye on them — they burn quickly.
