Russian Cuisine - Pomor Fish Soup

If you’re an assiduous reader of this blog, you might remember my first recipe for ukha, the traditional Russian fish soup: a yellow perch ukha with perch fritters and perch roe croutons. Freshwater fish soup is a fisherman’s classic, often prepared on the spot with the day’s catch over an open fire, and inseparable from the smell of woodsmoke. Since most Russians live inland (often very far from the sea), it makes sense that lakes and rivers would provide so much of the fish that locals eat. Yet, as we saw in my recent post on the Russian Far North, the Pomors, on the shores of the White Sea, are avid cod eaters. So it follows that Pomor ukha, made with seawater fish, is one of the most famous dishes in Northern Russian cuisine.

In fact, leafing through L.A. Cheryomukhina’s Severnaya Kukhnya (Northern Cuisine), one finds many recipes for northern ukha. Like everywhere else in Russia, these soups generally start with a fish broth, made either with whole small fish or the bones, fins, and heads of large fish, boiled with onion and parsley for about an hour, then strained. The “Arkhangelsk” ukha calls for a fish broth made of cod fins and bones, then chunks of cod, onion, finely chopped cod liver, scallions, dill, black pepper, and bay leaf. The so-called “Pomor” ukha consists of just boiling water into which are added sliced potatoes, peppercorns, chopped onion, and cod chunks, finished with hot milk, diced butter, and chopped herbs. These names aren’t mutually exclusive, though – you could be a Pomor and live in Arkhangelsk. Several variations simply mix and match from the above two recipes. Others throw their own curveballs: freshwater fish from the waters of Northern Russia, fish pelmeni instead of chunks of fish, breadcrumbs, lemon juice… One particularly interesting recipe from the Onezhsky District uses marinated saffron milk caps and dried small fish, and suggests serving the soup with a piece of coulibiac or other rybnik (fish pie). But what makes a northern fish soup specifically “Pomor” is the use of seawater fish, cod in particular.

You’ll find many of the aforementioned elements in my ukha: the cod fillet and cod liver, the potatoes and scallions, lots of herbs (Russians love their herbs), the milk, even a bit of the smokiness. Then there are my own touches:

  • While the fish broth is typically started with water and fish bones, I’m using chicken stock. Unbeknownst to many (sorry, pescatarians), the use of chicken stock in fish dishes is fairly common in high-end restaurants.
  • I borrowed from Darra Goldstein’s new cookbook Beyond the North Wind the idea of adding a pinch of saffron, to “turn the broth golden and reflect the influence of trade to Arkhangelsk from points east and west.”
  • I don’t like my fish overcooked or broken down into a dozen pieces in the soup bowl. For this reason, I’m cooking it very gently in a sous-vide pouch. As all the solid ingredients are assembled in the bowls before the liquid is added, you can pour the soup tableside for a more dramatic presentation.
  • I’m serving with a piece of French baguette toasted in butter, because a soup without toasted bread and butter, Pomor or not, isn’t worth eating!
