It’s like calling prison wine a delicacy. It’s something you’d make and consume to survive or out of some other kind of desperation. Why you’d choose to do so when there are other options…
In the comments on that Try video I posted, a couple of people said that when it’s consumed properly - with flatbread, chopped onions, and sour cream - it’s not bad. A few years ago in Iceland, I tried pickled herring at a breakfast buffet, and found it surprisingly palatable. Not anything I’d deliberately seek out, but I did go back for more. It had a mild, pleasant flavor, and was not disgusting at all.
I used to think anchovies were gross because I grew up hearing that anchovies were gross. Then I learned that one reason why Caesar dressing is so good is because of anchovy paste, and now I have a very good opinion on anchovies.
