Creamed horseradish is made with cream and often egg yolk. Plain grated horseradish carries neither.

Flags follow UK labelling rules and come from the ingredients as listed, not from any particular brand. Check the packet before cooking for somebody with an allergy.

Ingredients

Smoked mackerel50 g
As sold. Most of the fat in any dish it is in.
Cooked beetroot50 g
Vacuum-packed, not pickled. Pickled beetroot carries vinegar and usually sulphites.
Creamed horseradish1 tsp (6 g)
Rice cakes2 cakes, about 18 g
Rocket10 g
Lemon juiceA squeeze

Method

Flake the mackerel off its skin, feeling for bones as you go.
Dice the beetroot small and dry it on kitchen paper.
Spread the horseradish thinly over the rice cakes, then the rocket, beetroot and mackerel. Finish with lemon and eat at once.

Worth knowing

Smoked mackerel flakes and holds on a rice cake where tinned fish falls off. It is an oily fish, so 50 g is 150 kcal, and doubling it doubles that.
Creamed horseradish contains milk and egg. A scrape of grated fresh horseradish has neither, if that matters.
