Cut the bread rolls into slices and pour water over them, leave to swell. Express well. Cut the pickles into very fine cubes. Also cut the onions into fine cubes.
Heat 1 tablespoon butter and sweat the onions until translucent. Add parsley. Put the onion and parsley mixture in a bowl, add the rolls, pickles, minced meat, eggs and lemon juice. Season everything with salt, cayenne pepper and black pepper and knead vigorously.
Melt the rest of the butter, grease a mold. Shape the meat dough into a loaf and place in the pan. Bake on the lower rack for 30 minutes (fan oven 180 ° C), always brushing with the liquid butter.
Heat the meat stock and mix it with the cream, crème fraîche and paprika powder. (If you like a lot of sauce, you can simply double the amount of sauce). Pour the sauce over the meatloaf and cook for another 10-15 minutes.
