Bakalar na bijelo

The Christmas stockfish of Istria

Across the northern Adriatic, dried cod became a food associated with family gatherings, religious observances and winter meals.

In Istria, one of the characteristic preparations is bakalar na bijelo, literally stockfish prepared “in white.”

It is a creamy mixture of cooked preserved cod, olive oil, garlic and seasonings. Some versions add cooked potato.

Although it is sometimes compared to Venetian baccalà mantecato, the Istrian preparation has its own regional identity and serving traditions.

The texture can range from an oil-rich whipped fish cream to a substantial mixture containing pieces of fish and mashed potato.

It may be eaten warm or cold, spread onto bread, or served with vegetables, pasta and other accompaniments.

The defining features are the prepared fish, olive oil, a pale appearance and the process of breaking and beating the flesh.

Names across the northern Adriatic

In Croatian, bakalar commonly identifies cod as a fish or food ingredient.

In this culinary context, the traditional preserved form is particularly important.

The word bijelo, meaning white, distinguishes the preparation from bakalar na sugo, a sauced or stewed version often containing tomato.

The two forms are related by ingredient but differ substantially in texture and cooking method.

Croatian — Bakalar na bijelo

Croatian — Bakalar na bilo — regional/dialectal form

Istrian forms — Bakalaj, bakala

Italian — Baccalà or stoccafisso in regional usage

Slovenian — Bakalar, polenovka na belo

English — Istrian white stockfish spread

Scientific name — Usually Gadus morhua

The arrival of an imported fish

Cod does not inhabit the Adriatic in the way it inhabits the northern Atlantic.

The development of Istrian bakalar therefore depended on trade.

The broader Venetian and Adriatic commercial networks supplied preserved northern fish to communities around the coast.

Drying made cod transportable without the same immediate spoilage risk as fresh fish.

The preservation process also allowed it to become part of inland as well as coastal food culture.

Istrian historical accounts connect bakalar with Venetian maritime trade and with its later adoption into local domestic cooking.

The practice became particularly associated with Christmas Eve, known in Croatian as Badnjak, and Good Friday, Veliki petak.

Those occasions traditionally involved restrictions or customs relating to the consumption of meat in Catholic communities.

Fish could therefore occupy an important place at the festive table even far from the northern fisheries where it originated.

The available evidence supports these cultural associations but does not establish one exact year when the white beaten preparation first appeared in Istria.

It would be inappropriate to assign a medieval invention date without a recipe or other contemporary record.

Traditional preparation

The Istrian food encyclopedia Istrapedia describes a method in which dried cod is soaked, cooked, cleaned and then beaten in a wooden bowl.

A special wooden implement, resembling a robust spoon or ladle, may be used to work the flesh.

Olive oil is added generously as the fish is beaten.

The expression that the fish “drinks” the oil captures an important practical characteristic: the mixture takes up oil gradually as its structure changes.

Salt, pepper and garlic are central seasonings.

Chopped parsley is sometimes used.

Cooked potato is an optional traditional addition rather than an invention of the modern editorial recipe.

The potato helps bind the mixture and increases its volume.

That last point matters when interpreting regional variations. A potato-rich bakalar has a different texture and ingredient balance from a version made almost entirely with fish and oil, but both belong within the recognized family of preparations.

What happens during beating

Cooking first softens the hydrated fish and denatures its proteins.

Mechanical beating then breaks apart the muscle fibres.

As oil is added, the fish becomes coated and increasingly integrated into a cohesive mixture.

The preparation contains protein particles, water and dispersed fat.

Unlike a bread-based or flour-thickened sauce, its initial structure comes from the fish itself.

The addition of potato introduces gelatinized starch.

Cooked potato contains starch granules that have absorbed water and swollen during cooking.

When potatoes are mashed gently, they contribute bulk and viscosity.

This can make the mixture easier to spread while reducing the proportion of fish in each serving.

Excessive mechanical processing of potatoes is undesirable.

A blender can rupture too many cells, releasing additional starch into the mixture and giving it a gummy or gluey consistency.

Hand-mashing allows better control.

Garlic contributes pungent sulphur compounds. Its intensity depends upon how finely it is crushed and whether it is cooked.

Warming garlic briefly in oil produces a gentler result than incorporating it raw.

Olive oil determines much of the mouthfeel, making its flavour an important choice.

Recipe: potato-rich bakalar na bijelo

Serves 4 as a light main or 6 as a starter · 50–70 minutes after rehydration · Not kitchen-tested

Method

1. Cook the potatoes. Peel and cube the potatoes. Boil in water until completely tender.

Drain and allow steam to escape for approximately two minutes.

2. Mash by hand. Mash the potatoes without using a high-speed blender or food processor.

A potato masher or fork is sufficient.

3. Cook the fish. Place the prepared stockfish in the measured water and simmer gently.

Begin checking after 20 minutes and continue until the fish separates easily.

4. Reserve liquid. Keep 150 ml of the fish cooking water before draining.

Inspect the fish again for small bones.

5. Prepare the garlic oil. Warm the crushed garlic in 30 ml of the olive oil over low heat for approximately one minute.

Avoid browning it.

6. Beat the fish. While the fish is still warm, pound or beat it in a bowl.

Gradually incorporate the garlic oil.

7. Add remaining oil. Continue beating while adding the rest of the olive oil in small amounts.

The fish should become cohesive without turning completely smooth.

8. Incorporate potato. Fold in the mashed potato gently.

Add reserved fish liquid in approximately 15 ml increments until the mixture is soft enough to spread.

9. Finish. Stir in parsley, salt and pepper, and optional lemon juice.

Serve warm or chill promptly for later consumption.

The relatively high potato proportion is a choice made for this collection. It is not presented as the single authoritative Istrian ratio.

Why the potatoes are optional

Some bakalar preparations are primarily fish and olive oil.

They can be relatively fibrous and intensely fish-flavoured.

Potato-containing versions are milder and more substantial.

The starch also changes how the preparation behaves after cooling.

A mixture containing plenty of potato may firm noticeably in the refrigerator and become less readily spreadable.

Gently warming a portion can soften it, although repeated heating and cooling should be avoided.

The addition of potato also changes the ratio between fish proteins and fat, so the same quantity of olive oil will produce a different texture.

This is one reason traditional descriptions often describe adding oil as necessary rather than giving one universal volume.

Bakalar na sugo

The major regional alternative is bakalar na sugo.

In that preparation, cooked stockfish is incorporated into a sauce or stew, commonly involving onion, garlic, wine and cooking liquid.

Tomato concentrate or puréed tomato may be added, giving the finished preparation a reddish colour.

It can resemble a fish brodet or thick stew rather than a spread.

It is commonly eaten with polenta or potatoes.

Although it uses the same preserved fish, it should not be treated as merely the addition of one ingredient to white bakalar. Its preparation, final consistency and serving role differ.

The two dishes are useful companion references within a broader stockfish atlas.

Serving the white preparation

White bakalar is closely associated with festive meals, especially Christmas Eve.

It can be served alongside bread, vegetables or pasta.

Istrapedia records its consumption with regional pasta forms and greens.

Today it is also commonly offered as a spread or appetizer outside religious festivals.

Bread provides a neutral base for the rich mixture.

A small portion works well as part of a larger selection of dishes. Because the flavour is concentrated, large amounts are not necessary for the stockfish to be noticeable.

Quality checks

A successful white bakalar should be cohesive, pale and richly flavoured.

The fish must be fully tender.

The mixture should not contain bones.

Garlic should be noticeable without completely dominating the fish.

If the preparation is too firm, carefully incorporate a little reserved cooking liquid.

If oil visibly separates, further beating may be required, but adding more potato will not necessarily correct the underlying fat-water balance.

If potatoes become gluey, mechanical overprocessing is a likely cause.

If the mixture is watery, the fish or potatoes may not have been drained sufficiently.

Safety

Keep the fish below 4°C throughout hydration.

Cook fish thoroughly to the applicable safe temperature, with 63°C as the published general guidance.

Treat the finished spread as a perishable cooked seafood product.

Do not assume that adding oil, garlic or lemon juice creates shelf stability.

Store chilled if it is not served immediately.
