πŸ“ About This Recipe

A legendary seasonal delicacy from the heart of St. Petersburg, fried smelt is celebrated for its unique, refreshing aroma of fresh cucumbers. These small, silver-scaled fish are dredged in seasoned flour and pan-fried until the skin becomes golden and shatteringly crisp while the flesh remains tender. It is a rustic, soul-warming dish that signals the arrival of spring in Russia and is best enjoyed by the dozen with good company.

πŸ₯— Ingredients

Main Ingredients

  • 2 pounds Fresh Smelt (Koryushka) (cleaned and patted dry)
  • 1 cup All-purpose flour (for dredging)
  • 2 tablespoons Cornstarch (for extra crunch)
  • 1.5 teaspoons Sea salt (fine grain)
  • 1/2 teaspoon Freshly ground black pepper
  • 1/4 teaspoon Smoked paprika (optional, for a subtle depth)
  • 1/2 cup Sunflower oil (or any neutral high-smoke point oil)

For the Quick Tartar Sauce

  • 1/2 cup Mayonnaise (preferably Russian or European style)
  • 2 tablespoons Dill pickles (finely minced)
  • 1 tablespoon Fresh dill (finely chopped)
  • 1 teaspoon Lemon juice (freshly squeezed)

For Garnish

  • 1 Lemon (cut into wedges)
  • 1 sprig Fresh parsley (for decoration)

πŸ‘¨β€πŸ³ Instructions

  1. 1

    Thoroughly rinse the smelt under cold running water. If the fish are small, they can be cooked whole; if larger, remove the heads and entrails by making a small slit near the gills and pulling gently.

  2. 2

    Pat the fish extremely dry with paper towels. Removing excess moisture is the secret to achieving a truly crispy skin rather than a soggy one.

  3. 3

    In a large shallow bowl or a sturdy zip-top bag, combine the all-purpose flour, cornstarch, salt, black pepper, and paprika. Whisk or shake to ensure the seasoning is evenly distributed.

  4. 4

    Prepare the sauce by mixing the mayonnaise, minced pickles, chopped dill, and lemon juice in a small bowl. Cover and refrigerate until serving to allow flavors to meld.

  5. 5

    Place a few fish at a time into the flour mixture. Toss gently to coat every nook and cranny, then shake off any excess flour. The coating should be thin and even.

  6. 6

    Heat the sunflower oil in a large, heavy-bottomed skillet (cast iron is ideal) over medium-high heat. The oil is ready when a pinch of flour sizzles immediately upon contact.

  7. 7

    Carefully lay the smelt in the hot oil in a single layer. Do not overcrowd the pan, as this will drop the temperature and make the fish greasy; cook in batches if necessary.

  8. 8

    Fry the fish for 3-4 minutes on the first side without moving them, until the edges appear golden brown and crisp.

  9. 9

    Gently flip each fish using tongs or a fish spatula. Fry for another 2-3 minutes on the second side.

  10. 10

    Once the smelt are golden-bronze and stiff to the touch, transfer them to a plate lined with paper towels to drain any excess oil.

  11. 11

    Immediately sprinkle with a tiny extra pinch of sea salt while the oil is still hot on the surface.

  12. 12

    Repeat the process with the remaining fish, adding a little more oil to the pan if it starts to look dry.

  13. 13

    Pile the hot, crispy smelt onto a large serving platter. Garnish with fresh lemon wedges and a scattering of parsley.

πŸ’‘ Chef's Tips

Always use fresh smelt if possible; the signature 'cucumber' scent is a hallmark of freshness. Adding cornstarch to the flour creates a much crispier crust that stays crunchy longer than flour alone. Ensure the oil is hot enough before adding the fish; if it isn't, the flour will absorb the oil and become mushy. If you enjoy the traditional experience, leave the tails onβ€”they become like savory potato chips when fried crisp. Avoid covering the fried fish with a lid or foil after cooking, as the steam will soften the crispy coating.

🍽️ Serving Suggestions

Serve with a side of boiled baby potatoes tossed in butter and fresh dill. Pair with a cold, crisp Russian lager or a dry white wine like Riesling to cut through the richness. A side of fermented pickles or a light beet salad provides a perfect acidic balance. Offer plenty of lemon wedges for squeezing over the fish to brighten the flavors. Eat them with your hands for the most authentic and enjoyable experience!
