Clean, wash and shake spinach dry. Peel onion and garlic and dice finely. Heat the fat in a saucepan and sauté the onion and garlic for about 3 minutes. Add the spinach and let it collapse in a closed pot. Season to taste with salt and nutmeg
Wash lemon hot, grate dry and cut into slices. Wash salmon, dab dry, season with salt and pepper. Spread the spinach and salmon in a greased casserole dish. Mix crème fraîche, stock and white wine and distribute in the dish. Cover salmon with lemon slices
Cook in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 15-20 minutes. Bread tastes good with it
