For the Arctic char with potato-celery puree, preheat the oven to approx. 170 degrees with hot air. Wash the char and pat dry with a kitchen towel.
Salt and pepper the outside and inside. Then inside nicely distribute the herbs and the pressed 3 cloves of garlic. Fry in a pan with a little oil on both sides for about 5 minutes.
After frying, place the fish in an ovenproof dish with a little butter in the preheated oven. In the meantime, peel and wash the potato and the celery and cut them into small pieces.
Boil them in a small pot of salted water until soft. Heat the milk and the butter and grated nutmeg and mash it with the cooked celery and potatoes to a puree.
Wash the spinach. While it is draining, dice half an onion and 1 clove of garlic. Heat some oil in a pot, sauté the onion and garlic until translucent, then add the spinach.
Remove the char from the tube and serve with the puree and spinach.
