Smoked Mackerel, Beetroot, Potato and Horseradish Bake (from M&S)
(Serves 4)

500g Jersey Royal potatoes
100g cooked beetroot in natural juices
175g smoked mackerel
bunch dill
250ml double cream
150ml milk
1 tbsp horseradish sauce

Heat the oven to 190°C. Cook the potatoes in boiling salted water for 15 mins, until just tender. Drain well.

Arrange the potatoes in a baking dish with the beetroot. Remove any skin and bones from the mackerel and break the flesh into chunky flakes. Add to the potatoes and beetroot and scatter over half the dill.
