Cut the fillet into 8 pieces. Drizzle with lemon juice and season with salt. Peel or clean the carrots and spring onions, wash and cut into slices.
Heat the butter in the pan. Sauté the spring onion and rice in it. Add the carrots and frozen peas. Season with salt and pepper and drain off the broth. Bring to the boil and cook everything over medium heat for about 10 minutes. Place the fish on top of the rice and cook covered for another 10 minutes until the rice and fish are cooked through.
Wash dill, shake dry and finely chop.
Spread the créme fraîche on the fish. Sprinkle with dill and paprika powder. Garnish with lemon and dill blossom if you like.
