Mix the milk with 300ml of water together, pour it into a large shallow pan and bring to the boil

Add the bay leaves, onion slices and peppercorns and bring back to the boil

Add the white fish and simmer gently. Poach for about 3-4 minutes, until the fish is cooked

Lift the fish out on to a plate and leave until cool, then break into flakes, discarding any skin and bones

Pre-heat the grill to high

Whisk the eggs together with some seasoning

Heat a 23-25cm non-stick frying pan over a medium heat, then add the butter and swirl it around to coat the base and sides of the pan

Pour in the eggs and, as they start to set, drag a wooden spoon over the base of the pan, lifting up little folds of egg to allow the uncooked egg to run underneath

When the omelette is set underneath but still very moist on top, sprinkle over the flaked fish and feta

Pour the cream on top, sprinkle with parmesan cheese and put the omelette under the hot grill until lightly golden brown

Slide it on to a warmed plate and serve
