I didn't know what this was when I got it. Thank goodness sleď turned out to be herring! This variation on "fish salad" — one variety of the mayo-salad, a lovely central European (and, of course Midwestern) speciality — turned out to be herring fillets in dill sauce. I was afraid it would be smelt, even though I couldn't really imagine "smelt salad."
