I have had a number of Jewish people request fresh Lake Whitefish from me specifically to make gefelta fish. Never tried it myself but am not repulsed by it.
My earliest memories of my Norwegian Grandmother holding my nose so I would open my mouth so she could shovel in some lutefisk. I don’t know how old I was but I was strapped into a high chair at the time. I tried but that woman went to her grave with no forgiveness from me.
