What is Surströmming?

My first reaction was an ewww but I use worceshtershire sauce all the time for roasts. So I guess I'm a fan of Fermentation. I love sauerkraut with pork .

Always Check the label. Good Worcestershire sauce uses anchovies in its production process. Obviously those with fish allergies should not use it, but not everyone knows that. I ended up in the ER many years ago because we didn't know.

so worcestershire Sauce had a fermented fist in it ..is it like patis in philippines
