I bought 3 bottles of Abba herring yesterday, each at $3.50. It tastes great, though a bit sour, since it's preserved in part with vinegar.

So, what I bought is, one bottle of herring in tomato, one bottle in dill marinade with onion and potatos, and one bottle in dill marinade.

While eating the tomato herring, I decided to google for the herring, and found something interesting!

Some fish pass wind to communicate! If you're interested in hearing fish (specifically, herrings) fart, try this out!
