A great fish recipe to make yourself:
Peel the potatoes and cook them in salted water. Season the herring fillets with salt and pepper, roll in mustard and cover with the chopped onions. Now roll the fillets in flour, pull them through beaten egg and fry them in hot oil until golden brown. For the sauce, extinguish the frying fat with water, season with sugar and lemon sweet and sour, season with salt and pepper. If necessary, thicken the sauce with sauce thickener. Mash the potatoes with milk and butter. Serve the herring fillets with a little sauce, mashed potatoes and chopped parsley.
