It's a must for a bloody mary. If it weren't for the list of ingredients, you wouldn't know there's fish in it at all.
I know it. Anchovies are in a lot of things you wouldn't think of. Mostly because of Worcestershire sauce. You're right it's part of what makes a bloody mary good. I bet though, If it was a called a tomato cocktail with fish juice.. we would have never tried it to begin with. Haha
