Baccalà Mantecato with Cornichons and Walnuts
A velvety emulsion of rehydrated salted cod, olive oil, and milk, whipped until light as a cloud. This Friuli-Venezia Giulia specialty balances the deep salinity of the fish with the sharp tang of fresh cornichons and the earthy crunch of toasted walnuts.
A little context
Originating in the Venetian and Friulian traditions, Baccalà Mantecato has been a staple since the 16th century when salted cod from Norway was imported via the Adriatic. Traditionally served as an antipasto on polenta, it is the centerpiece of Christmas Eve dinners and festive gatherings in the region. Authentic preparation relies on patience: the cod must be soaked for three days to remove excess salt before being slowly poached and vigorously whisked to create its signature foam-like texture.
Method
- 01
Prepare the Cod
Ensure the salted cod has been desalted by soaking in cold water for 48–72 hours, changing the water every 8 hours. Pat the fish completely dry, remove any remaining skin and bones, and flake the flesh into large chunks.
- 02
Poach the Fish
Place the flaked cod in a small saucepan and cover with the warm milk. Simmer gently over low heat for 10–12 minutes until the fish is tender and easily flakes apart. Do not let the milk boil vigorously.
- 03
Drain and Cool
Remove the pan from heat. Carefully pour the mixture through a fine-mesh sieve into a bowl, reserving about 30 ml (2 tbsp) of the cooking milk. Let the fish cool slightly, then transfer it to the food processor or stand mixer bowl.
- 04
Begin the Whip
Start the mixer on medium speed. Begin adding the room temperature olive oil in a very slow, steady stream, just as you would when making mayonnaise. The mixture will start to thicken and turn white.
- 05
Emulsify
Once the oil is incorporated, add the softened butter (if using) and the reserved warm milk gradually. Continue to whip on medium-high speed for 5–7 minutes until the mixture is completely smooth, pale, and has doubled in volume, resembling a thick mousse.
- 06
Season and Fold
Taste the mixture; only add salt if absolutely necessary. Gently fold in the diced cornichons and half of the toasted walnuts, reserving the rest for garnish.
- 07
Chill and Serve
Transfer the Baccalà Mantecato to a serving bowl. Cover and refrigerate for at least 30 minutes to allow the flavors to meld and the texture to set. Before serving, top with the remaining walnuts and a drizzle of extra virgin olive oil.
Pro tips
- ✦The success of this dish depends on the temperature of the oil and milk; if they are too cold, the emulsion will break.
- ✦If the mixture looks curdled, stop adding oil and whisk in a tablespoon of warm milk to bring it back together.
- ✦Do not skip the desalting process; under-soaked cod will be inedibly salty, while over-soaked cod will lack character.
- ✦Serve strictly at room temperature; chilling it too long will harden the fats and ruin the creamy texture.
- ✦Use a high-quality, peppery olive oil as it is the primary flavor carrier in the finished dish.

Substitutions
- cornichons → finely chopped capers or gherkins (capers offer a saltier, brinier punch; gherkins are closer in texture)
- walnuts → toasted pine nuts or hazelnuts (pine nuts are more traditional in Veneto; hazelnuts offer a sweeter crunch)
- butter → extra 20 ml (1 tbsp) olive oil (makes the dish strictly dairy-free while maintaining creaminess)
Storage
Refrigerate in an airtight container for up to 2 days; stir gently before serving. Do not freeze as the emulsion will separate upon thawing.
What to serve with it
- Soft polenta or grilled rustic bread
- Chilled Prosecco or a crisp Friulano white wine
- Fresh arugula salad with lemon vinaigrette
FAQ
Can I make this without a food processor?+
Yes, but it requires significant effort. Use a wooden bowl and a strong whisk, adding the oil drop by drop while whisking vigorously for 15–20 minutes until fluffy.
My cod is still too salty after soaking.+
Soak it in fresh cold water for another 12 hours, changing the water every 3 hours. Test a small piece by cooking it plainly before proceeding.
Why did my emulsion break?+
The oil was added too quickly or the ingredients were too cold. Fix it by starting a new bowl with a teaspoon of mustard or a splash of milk, then slowly whisking the broken mixture into the new base.
