As a former Son's of Norway member, I took a solemn pledge to be completely serious when it came to lutefisk.  My first two years as a member, I worked in the kitchen at their annual lutefisk dinner.  I didn't just work in the kitchen, I stood over the fillets and broke them apart after they came out of the boiling pot of water (I did this for several hours 🤢).  I learned early on, that if they came out of the pot early enough they looked like normal cod .............................. but for those pieces that stayed in a minute too long, you were working with a gross gelatin looking mass.  I tried some of the normal fillets - they tasted fine (just hold your nose to avoid the smell from the kitchen).  You couldn't pay me enough to try those gelatin masses.
