A recipe I got from folks here is based on potatoes, onion and fish.
I like some more vegetables in my chowder and added carrots and celery, (and/or leeks).
That's more like the Norwegian "Bergen's Fiskesuppe" (fish soup from Bergen).
First, sautée onion and bacon in butter until the onions are turning yellow. Ca 3 min.
Add diced carrot, celery and potatoes. Fill up with some water and simmer until potatoes are nearly done. Season with salt and herbs. Ca 10 min.
Add warm milk and pieces of fish and, continue to simmer until the fish is done (ca 10 min). Thicken the soup with corn starch if desired.
Voilà!
