Dunaiskyi Oseledets (дунайський оселедець, salted Danube herring)

Ingredients

Equipment Needed

• •A glass or enamel dish deep enough to submerge the fish
• •A small plate or fermentation weight
• •A sharp filleting knife
• •Tweezers for pin bones

Instructions

1. 1

   Clean the fish

   Rinse the fish under cold water, then pat them dry. If they still have heads, remove them, slit the bellies, and clean out the blood line carefully with your thumb or the back of a small knife. That dark line is where muddy bitterness hides, and you don't want it in the cure.

   Use the freshest fish you can. The eyes should be clear, the skin bright, and the smell clean, like cold water and oil, not sour.
2. 2

   Make the brine

   Stir the salt and tablespoon of sugar into the cold water until dissolved, then add the bay leaves, peppercorns, coriander seeds, and the small sliced onion. Taste the brine with the tip of your tongue. It should be clearly salty but not brutal, like seawater that has learned manners.

   This is a light cure, about 6 percent salt against the water. It firms and seasons the fish without turning it into something you must soak for half a day.
3. 3

   Cure the herring

   Lay the fish in a glass or enamel dish and pour the brine over so they are fully covered. Weigh them down with a small plate if they float, cover, and refrigerate for 2 to 3 days. Turn them once a day. They are ready when the flesh feels springy, the skin has tightened, and the smell changes from raw fish to clean, salted richness.

4. 4

   Soften the onion

   An hour before serving, toss the serving onions with the vinegar, teaspoon of sugar, a pinch of salt, and half the dill. Scrunch them lightly with your fingers until they relax and shine. If your onions are very sharp, rinse them first with cold water, then dress them. We are cutting the fish's oiliness, not setting fire to the table.

5. 5

   Fillet and slice

   Lift the herring from the brine and pat dry. Fillet them with a small sharp knife, pulling out the fine pin bones you can feel, then slice the flesh on a slight diagonal into generous pieces. Taste one piece before you dress the rest. If it is saltier than you like, give the fillets a brief cold-water rinse and pat them dry again.

6. 6

   Dress and serve

   Spread the softened onions over a shallow stoneware plate, lay the herring pieces on top, and spoon over the unrefined sunflower oil until the fish gleams. Scatter with the remaining dill. Serve cold with boiled potatoes and black bread, enough for eight guests or one hungry Ukrainian.

Chef Tips

• •If you cannot get Danube herring, use the freshest small oily herring, shad, or mackerel you can find. It becomes a bit more modern and less local, but the method still teaches you the southern table.
• •The curing time bends with the fish size. Thin fish may be ready in 36 hours; thick ones may need 3 days. Press the flesh gently: raw softness means wait, a springy satin feel means eat.
• •Do not cure fish that smells tired. Salt preserves good fish, it does not rescue bad fish.
• •Unrefined sunflower oil matters here because it goes on raw. It is Ukraine in a bottle of oil, green-gold, nutty, and loud enough to stand beside the herring.
• •Leftover cured herring keeps 3 days in the fridge under a film of sunflower oil with onions on top. After that it gets stronger, and not always in a charming way.

Advance Preparation

• •The herring needs 2 to 3 days in the refrigerator to cure, so start it before the day you want to serve it.
• •The onions can be dressed up to 4 hours ahead and kept chilled; they get softer and sweeter as they sit.
• •Cured fillets can be sliced and laid under sunflower oil the morning of serving.
