Smoked cod fish cakes

1) Mash the leftover potato with the butter and cream, season to taste.
2) Lightly fry the cod fillet in half of the oil until it flakes easily.
3) Add the egg and the flaked cod to the potato, add a little flour if it seems too loose.
4) Heat the oil in a frying pan over a medium heat.
5) Divide the mixture into four and pour into the warmed oil. You may need to do 2 at a time depending on the size of your pan.
6) Fry lightly for 8 minutes each side or until nicely browned (keep the fish cakes moving in the oil to prevent sticking).
7) Serve with a salad of your choice. We served ours with wilted spinach and cherry tomatoes.
