I got the idea for this salad from Chainaia Lozhka, a Russian fast food chain where I had lunch one day in St. Petersburg. Chainaia Lozhka (Russian for teaspoon) sells exclusively blini and salads, including this nice beet and herring combo. It’s no secret that I like the Russian way with beets and smoked fish, so I don’t know why I didn’t think of this myself.
This salad is really an informal version of seledka pod shuboi, a multi-layered, herring-beet-vegetable dish served on special occasions. Just mix all the ingredients and the dressing in a bowl instead of layering them in a dish. You could even forgo the potatoes for a lighter version.
