I wonder about that. I recently read the book My Life With The Eskimo, by Vilhjalmur Stefansson. He lived with the Eskimo before World War 1 for a long chunk of time - I think about 5 years. As far as I remember he didn't mention food like that. Lots and lots of boiled fish, though, and caribou.

If you're interested, it's available on annas-archive.org (https://annas-archive.org/md5/eec5a2359ef12238d79a94317989b6f6). It's a really interesting book, all about the life of the Eskimo, just before they had significant contact with explorers/whalers.
