Beat the egg until frothy, mix with the crème fraiche and season with salt, pepper, marjoram and nutmeg.
Peel the potatoes, grate them medium coarsely and squeeze them out in a kitchen towel. Mix with the egg mixture. Line a loaf pan with baking paper and pour in the mixture.
Bake in a hot oven at 190 ° C for about 25 minutes. Then cover with aluminum foil and bake for another 10 minutes.
Let the terrine cool down and turn it over - the foil is easy to peel off when it is lukewarm. Cut the cooled terrine into approx. 1 cm thick slices and fry in a pan in hot butter or oil.
Goes very well with fish, game and poultry, but also with vegetable dishes.
