Wash and cut the fish into acceptable portions depending on who you are cooking for

Put the oil and chile flakes into a pan. Slice the spring onions and add. Cook over a moderate heat, stirring now and then. In your spare moments, grate the cheese. When the onions are soft, turn the heat off and drain any excess oil

And add to the pan. Turn the heat up for about 5 minutes until the wine has evaporated

Dissolve the cornflour in the slosh of white wine in a glass

Add the milk to the pan. Turn the heat up and when it starts bubbling

Add the grated cheese

Stir well over a very low heat, so that the cheese melts gently

Add the cornflour dissolved in wine and stir well

Once the sauce has thickened over a gentle heat and with constant stirring

Add a dollup of natural yoghurt and stir again

Taste and add salt and pepper if you prefer. If I had had chives or fresh parsley then I would have added at this point.

Serve and enjoy :-)
