Lutefisk is a kind of fish that has been prepared in a special way that makes it different from other fish you might have tried.
First, the fish is soaked in a mixture of water and lye, which is a chemical that makes things very slippery and can be dangerous if not handled correctly. This makes the fish become jelly-like and soft.
Then, the fish is rinsed many times to wash away the lye and any other things that might be on the fish. This can take a long time and needs to be done carefully so that the fish doesn't fall apart or get too dry.
Finally, the fish is usually cooked in the oven with butter, salt, and pepper. Some people think the taste is very strong and salty, while others really like it.
Overall, lutefisk is a kind of fish that has been specially prepared using lye to make it soft and then cooked in the oven with butter, salt, and pepper. Some people like it, while others find the taste too strong.
