Also used to filter wine - see https://www.winespectator.com/articles/are-egg-whites-really...

Yes, that's also where the french dessert canelé comes from: the egg whites being used for wine filtering, you have a lot of yolks left. So instead of wasting them, they were/are used to make canelés.

And Swedish egg coffee.

Which funnily is absolutely not a thing here in Sweden.

First time I heard about "Swedish egg coffee" from American colleagues I was really puzzled, had to do some research about it because I never heard or seen it. It seems to come from some Swedish immigrants to the USA that used eggs instead of fish skins to remove impurities from coffee.

Interesting! I first saw it at a state fair in the US. They mentioned Swedish immigrants too, but didn't say whether they invented the technique.

I was skeptical but...it's actually great.

Wait, so swedish fish coffee is the real deal?

In the 19th century, for sure!
