Jacket Potatoes with Leeks and Mackerel

Jacket Potatoes with Leeks and Mackerel

4 Baking Potatoes
2 Leeks sliced
2 tbsp creamed horseradish
4 smoked mackerel
lemon juice
50g butter

Bake the potatoes in oven. 
Heat butter in pan and cook the leeks for about 5 minutes, add the horseradish, flaked fish and lemon juice. Season with pepper.
Halve the potatoes and mash the top with a fork, spread mixture on top and serve.

From  Moneysavingexpert you could also use sliced spring onions in place of the leeks and tinned fish (NOT the kind in tom sauce!) in place of the mackerel or kippers in place of the mackerel.
