• 1 small onion, thinly sliced (for soaking)
• 1 tsp fine sea salt
• 1/2 tsp freshly ground black pepper

• 500 g (1.1 lb) cooked beets, peeled and coarsely grated (about 3–4 medium)
• 1 small onion, finely chopped
• 2 tbsp unsalted butter
• 1–2 tbsp apple cider vinegar, to taste
• 1 tsp sugar
• 1/2 tsp fine sea salt, plus more to taste
• 1/4 tsp black pepper
• Optional: 1–2 tsp prepared horseradish for gentle heat

Boiled Potatoes with Dill

• 800 g (1.75 lb) baby potatoes, scrubbed
• 1 tbsp unsalted butter
• 2 tbsp fresh dill, finely chopped
• 1 tsp fine sea salt (for the water), plus a pinch to finish

Step-by-Step Instructions

Step 1: Prep the carp and mellow its flavor

Cut the carp into 4 even pieces if needed. Check for pin bones and pull them with clean tweezers. In a shallow dish, combine milk and sliced onion, then submerge the fish. Soak for 30 minutes to gently tame any muddy notes. Lift out, discard the milk and onion, and pat the fillets thoroughly dry with paper towels. Season both sides with 1 tsp salt and 1/2 tsp pepper.

Step 2: Start the potatoes

Place baby potatoes in a pot, cover with cold water by 2–3 cm (1 inch), and add 1 tsp salt. Bring to a boil, then simmer gently until just tender, 12–15 minutes depending on size. Drain and return to the warm pot; cover to keep hot.

Step 3: Make the warm beet salad

In a medium skillet over medium heat, melt 2 tbsp butter. Add the chopped onion and cook until translucent, about 2 minutes. Stir in grated cooked beets, 1 tbsp vinegar, 1 tsp sugar, 1/2 tsp salt, and 1/4 tsp pepper (plus horseradish if using). Warm, stirring occasionally, 6–8 minutes until glossy and steaming. Adjust acidity with more vinegar and salt to taste. Keep warm over very low heat or cover.

Step 4: Set up the breading station

Arrange three shallow dishes: flour in the first, beaten eggs in the second, and breadcrumbs in the third. Dredge each seasoned fillet in flour (shake off excess), then dip in egg, and finally press into breadcrumbs to coat evenly. Set on a wire rack for 5 minutes to help the coating adhere.

Step 5: Heat the pan for frying

Pour 120 ml (1/2 cup) clarified butter or neutral oil into a large heavy skillet to a depth of about 3–5 mm (1/8–1/4 inch). Heat over medium to medium-high until the fat reaches 180–190°C (350–375°F). If you do not have a thermometer, a breadcrumb should sizzle briskly and brown in about 45 seconds.

Step 6: Fry the carp to a crisp, golden finish

Lay the breaded fillets in the hot fat, skin-side down first. Fry 3–4 minutes per side until deep golden brown and the fish flakes easily with a fork (internal temp about 60°C/140°F). Work in batches to avoid crowding, adding more fat as needed and returning to temperature between batches. Transfer to a rack set over a sheet pan and keep warm in a 90°C (200°F) oven while you finish the rest.

Step 7: Finish the potatoes and serve

Add 1 tbsp butter and chopped dill to the hot potatoes and toss with a pinch of salt. Plate the carp with lemon wedges, a scoop of warm beet salad, and the dill potatoes. Squeeze lemon over the fish right before eating for that bright, classic Wigilia finish.

Pro Tips

• Dry fish = crisp crust. Blot very well after the milk soak so the breading adheres and browns evenly.
• Mind the oil temperature. Keep it near 180–190°C; too cool and the coating gets greasy, too hot and it burns.
• Use clarified butter for flavor and higher smoke point, or blend it 50/50 with neutral oil.
• Rest breaded fillets 5–10 minutes before frying to lock on the crumb.
• Keep it hot and crisp by draining on a wire rack, not paper towels, and holding in a low oven.

Variations

• Flour-only coating: For an even lighter crust, skip breadcrumbs and use only seasoned flour.
• Gluten-free: Use a 1:1 gluten-free flour and GF breadcrumbs or fine cornmeal.
• Horseradish beets: Stir 1–2 tsp prepared horseradish into the beets for a traditional, gently spicy note.

Storage & Make-Ahead

Refrigerate leftovers in airtight containers up to 2 days. Reheat carp on a wire rack at 200°C (400°F) for 8–10 minutes to re-crisp. Beet salad reheats well on the stovetop over low heat, adding a splash of water if needed. Potatoes are best fresh, but you can parboil them a day ahead; rewarm and finish with butter and dill before serving. You can bread the carp up to 2 hours ahead; keep it uncovered on a rack in the fridge.
