Instructions
Dice the fennel and peel and dice the shallot.
Melt the butter in a saucepan over a medium heat then add the shallot and the diced fennel and sauté for about 5 minutes until the shallot and fennel are softened but not coloured.
Add the flour and cook, stirring for 2 minutes.
Gradually stir in the stock, then stir the sauce over a medium heat for about 10 minutes until thickened.
Stir in the cream.
Transfer to a blender and blend until smooth or use an immersion blender.
Check the seasoning and return to the pan.
Dry the halibut fillets well with kitchen paper then season with salt and pepper.
Heat the oil in a frying pan over a medium to high heat and add the halibut skin side down.
Cook for 3-4 minutes until golden then turn over and cook for 2-4 minutes until opaque.
At this stage the fish should be cooked. However, for thicker pieces of fish place in the oven at 180 C / 350 F / 160 FAN / Gas 4 until the internal temperature reaches 63 C or 145F.
Allow the fish to rest for a few minutes before serving with the sauce.
