Śledź w Śmietanie (Herring in Sour Cream)

Step 1

Place the drained herring fillets on a cutting board. Cut each fillet crosswise into 1-inch-wide pieces, cutting perpendicular to the length of the fish.

Step 2

Place the yellow onion root-side down on a cutting board, then slice lengthwise from root to tip into 1/8-inch-thick half-moons, about the thickness of a coin.

Step 3

Cut the apple half lengthwise in half again, then slice each quarter crosswise into 1/4-inch-thick slices, discarding any remaining seeds.

Step 4

Pour the sour cream into a medium bowl. Add the herring pieces, sliced onion, apple slices, and chopped dill to the bowl.

Step 5

Stir gently with a rubber spatula, lifting from the bottom and folding everything together until the herring, onion, and apple are evenly coated with sour cream, about 30 seconds.

Step 6

Taste one piece of herring with a small spoon. If it needs more salt or pepper, sprinkle a pinch and stir again.

Step 7

Divide the herring mixture into four small bowls or plates, spooning equal amounts of sauce over each serving. Serve immediately or cover and refrigerate for up to 2 hours.
