- 300ml/10fl oz milk
 - 200g/7oz un-dyed smoked haddock
 - 1 bay leaf
 - 10 black peppercorns
 - 4 free-range eggs
 - 40g/1½oz butter
 - 15g/½oz plain flour
 - 50g/1¾oz grated mature cheddar cheese
 - sea salt and freshly ground black pepper
 
- Pour the milk into a large shallow pan, then add the smoked haddock, bay leaf and peppercorns and bring to a simmer.
 - Cook for five minutes, or until the fish has just cooked through and flakes when pushed gently.
 - Lift the fish out of the pan and set aside to cool slightly before gently flaking, discarding the skin.
 - Meanwhile, strain the milk into a clean pan and beat the eggs together in a separate bowl.
 - Heat a frying pan until medium-hot, add 15g/½oz of the butter and the eggs and cook gently, stirring with a fork until they just hold together.
 - Add half the flaked fish to the top of the omelette, then roll out of the pan onto an ovenproof serving dish and top with the remaining fish.
 - Preheat the grill to hot.
 - Wipe out the omelette pan and add the remaining 25g/1oz butter and melt, then add the flour and cook stirring well for two minutes. Gradually add the milk, whisking all the time until it forms a smooth sauce. Season the sauce with salt and black pepper. You can add a knob of butter at this stage too if you want to.
 - Pour the sauce over the top of the omelette, then scatter the grated cheese over the top and place under the grill for 3-5 minutes, or until golden-brown and bubbling.
 - Serve immediately.
