John Dory with Mussels

125 g butter
2 shallots, sliced
2 garlic cloves, sliced
2 celery sticks, sliced
250 ml of dry cider
100 ml of double cream
1 celeriac, small
40 green-lipped mussels, cleaned & de-bearded
8 fillets of John Dory
1 tbsp of olive oil
500 g of spinach, stalks removed & washed
SIDS SALT & PEPPER to taste
10 chives, finely sliced
2 Granny Smith apples, cut in 5 mm dice
¼ tsp SIDS CRAZY LEMON

Place 100 g of the butter into a pan and melt gently. Sweat down the shallots, garlic and celery until soft but not coloured.
Add 200 ml of the cider and Bring to the boil and cook very slowly for 15 minutes.
Strain through a sieve lined with a muslin cloth into a pan. Reduce the stock over a medium high heat to 250 ml. Add the double cream, re-boil and set to one side.
Cut the celeriac into 5 mm dice and cook in boiling salted water. Refresh in iced water then drain and set to one side.
Heat a pan with a lid and add the cleaned mussels. Pour in the remaining cider and cover with the lid so that the mussels steam open very quickly.
When the shells have opened, tip them into a colander set in a bowl to retain the liquid.
Remove the mussels from the shells and put to one side. Pass the liquid through a sieve lined with six layers of muslin cloth and set aside.
To cook the fish, get a large non-stick pan and add the olive oil. Place the fish into the hot oil skin side down, lightly sprinkle with SIDS CRAZY LEMON and pan fry gently until half cooked.
Turn the fish over and remove the pan from the stove, the fish will cook through in the residual heat.
Wilt the spinach in the rest of the butter and season with SIDS SALT & PEPPER.
Bring the sauce up to the boil and add some of the mussel stock to taste. Add the celeriac, apple and mussels, bring back to the boil then add the chives.
Divide the spinach between four bowls, arranging it in mounds in the centre of each bowl.
Pour the sauce around and arrange the apple, celeriac and mussels around the bowls.
Place two fillets of John Dory per portion on the spinach and serve immediately.
