Onion

Bake the herring fillet in the oven at 220-240 degrees for about 20 minutes or even longer, until it is very nicely cooked, but DOES NOT BURN. Be sure to monitor the situation. Chop the onions into small pieces, the fastest and most efficient way is with a chopper, but of course you can also use a knife. When the herring is cooked, mash it together with the onions, pour over ice water, add dill and lemon, as well as vinegar and salt. TASTE… so that it is refreshing and so that after tasting it you want to eat, that's how it should touch that heart 😀 Garnishes to taste… boiled potatoes, fried potatoes, chestnuts…
