The difference between pan-fried crucian carp in sour cream and braised crucian carp is exactly a hundred milliliters of water. With it, the sour cream stops being a coating and becomes gravy, the fish finishes cooking in liquid, and the crisp crust softens completely.

This is a trade, not a recipe mistake. In return, the crucian carp comes out softer and less dry, and there's enough gravy for a side dish — with potatoes or porridge it works better than any sauce made separately.

The onion is fried before the fish and returned at the end. Added together with the crucian carp, it would spend all twenty minutes on the heat and burn; added at the end, it stays soft and sweet.

Skip the water on the same pan and you get a different dish: crucian carp in sour cream with onion keeps its crust. Crucian carp with potatoes in sour cream sauce puts a potato layer under the fish instead.

Ingredients

Crucian carp – 5 pcs.
Warm water – 100 ml.
Sour cream – 150 g.
Onion – 1 pc.
Salt – to taste.
Ground black pepper – to taste.
Fish seasoning – to taste.
Wheat flour – 3 tbsp.
Vegetable oil – for frying.

Clean the crucian carp

Scale the fish, gut it, and cut off the heads and tails. Rinse and pat dry with paper towels.

Season

Put the crucian carp in a bowl, salt, pepper, add fish seasoning, and rub it into the fish.

Coat in flour

Pour flour onto a plate and generously coat each fish on both sides.

Fry the onion

Heat oil in a pan, cut the onion into half-rings, and fry until golden.

Fry and braise the fish

Remove the onion, add the crucian carp, and fry until crusted on both sides. Then spread sour cream on top, pour in warm water, and braise covered.

Return the onion

Put the fried onion back with the fish and braise for another couple of minutes.

Serve

Serve the crucian carp with the gravy, sprinkled with herbs.

Notes

There won't be a crust here. The water and the lid rule it out completely. Want it crisp — cook the crucian carp without water, that's a different recipe.
Use warm water. Cold water in a hot pan drops the temperature and stalls the process for a minute or two.
Lay the crucian carp in a single layer. Stacked on top of each other, they don't braise, they steam, and the bottom ones fall apart.
Cut off the heads and tails. Not for the taste, but for space: five whole crucian carp won't fit in a pan in a single layer.
Water doesn't forgive low-fat sour cream. Low-fat sour cream thinned with water separates instantly.

Questions and Answers

How long to braise crucian carp?

Seven to eight minutes covered, after the fish has browned on both sides, plus another couple of minutes together with the returned onion.

Why add water?

To turn the sour cream into gravy. Without water, the sour cream stays a coating on the fish rather than a sauce for the side dish.

Will there be a crisp crust?

No. Under the lid with water it softens. That's the price of tenderness and the gravy.

How many crucian carp fit?

As many as fit in a single layer. That's the main limit of the recipe, not the portion size.
