During my vacation Iceland from April 18 to 24, one of the first things I did was visit a grocery store. Naturally. Stuck in the wall of mayonnaise and mayo-based sauces in Bónus, I spotted hamburger sauce, hamborgarasósa. This Icelandic dictionary tells me that it at least has water, egg yolk, tomato concentrate, mustard, vinegar, and spices in it. ...Nom, nom!
Stay tuned for my Icelandic burger review later this week.
