Clean the fish fillet, season with salt and place in a baking dish. Tear off the orange peel with a zest and then squeeze out the juice. Mix the two together. Peel the ginger, chop it very finely (atomize) and add it, as well as the pepper.
Pour this stock over the fish fillets and let it steep for about 1/2 hour.
Then cook in a preheated oven at 200 ° C for approx. 20 minutes.
Note: If you don`t have a zester, take a grater or thinly cut the peel and cut into strips. However, be careful: do not use the bitter white below the skin!
