• 100 g all-purpose flour
• 5 g salt
• 60 ml vegetable oil
• 1 lemon, cut into wedges
• Fresh herbs (dill or parsley)

How Koryushka, Saint Petersburg Is Made

Step 1: Rinse and clean

Wash it, remove the head and guts. Because the fish is tiny, most of the skeleton is edible and will crisp into calcium-rich crunch as it fries—there is no need to fillet. Place cleaned fish on paper towels to dry slightly.

Tip: Do not scale the fish; the delicate skin adds flavor and texture.

Step 2: Prepare the coating

Mix flour and salt in a shallow bowl. This simple coating is traditional in Saint Petersburg.

Tip: Do not use breadcrumbs; the flour crust should stay thin.

Step 3: Coat the fish

Working in batches, toss the cleaned koryushka in the flour-salt mixture until lightly covered on all sides. Shake off any excess.

Tip: Leave fish whole—do not fillet or cut them.

Step 4: Heat the oil

Pour vegetable oil into a wide, shallow pan and heat over medium-high heat until shimmering but not smoking. The oil should be about 1 cm deep.

Tip: Use a neutral oil with a high smoke point, such as sunflower or vegetable oil.

Step 5: Fry the fish

Carefully add the coated koryushka to the hot oil in a single layer. Fry for 1–2 minutes until the undersides turn golden, then flip gently and fry for another 1–2 minutes until both sides are crispy and the bones turn translucent white.

Tip: The crushy, golden delicacy will cook very quickly because the fish is so small.

Step 6: Drain and serve

Transfer fried koryushka to paper towels to drain briefly. Arrange on a plate and serve immediately while still hot. Scatter with fresh herbs and serve with lemon wedges.

Tip: It's best served hot, and with a cold beverage of your choice.

Variants

• "Koryushka a la Riga" – a dish that originated in the Latvian capital city of Riga. In this recipe, Koryushka is lightly dusted with flour, pan-fried until crispy, and served with a generous dollop of sour cream and a side of boiled potatoes. The combination of the crispy fish, creamy sour cream, and hearty potatoes creates a perfect balance of flavors and textures.
• Dried koryushka (salted and air-dried for several days), eaten as a snack with beer.
• You can still buy it smoked, dried, or canned off-season when fresh fish is unavailable.

Common Mistakes to Avoid

• Scaling or filleting the fish: leave them whole. The tiny bones become edible and the skin adds flavor.
• Overcooking the fish: because they are so small, koryushka cooks in just a few minutes. Watch carefully to avoid drying them out.
• Using cold oil: the oil must be hot enough to sizzle immediately when the fish enters the pan, otherwise they will be greasy rather than crispy.
• Removing the head before cooking: the head and guts add flavor. Remove them only if you strongly prefer—locals eat them whole.
• Adding complex seasonings: The traditional way of cooking and serving smelt in St. Petersburg is marinated and fried. Fish (preferably not very large ones) are washed, rolled in flour and left whole to fry on both sides in vegetable oil. Stick to salt, flour, and oil.

How to Order and Eat It

Eat koryushka by hand, picking up the whole fish and biting into the crispy body. The bones and head are edible and become tender and crunchy when fried. Squeeze fresh lemon over the fish for acidity. Traditionally, koryushka is eaten as a shared plate—multiple fish piled together for diners to grab by the handful. Pair with cold beer, kvass, or vodka.
