Last night after the delicious ravioli with gorgonzola and witlof we had this simple but good dish that went nicely with the same wine (Erbaluce di Caluso).
This was my first attempt at sous-vide cod and it turned out perfectly cooked with a great texture. However cod is so flaky that it seems impossible to sear the fish after cooking sous-vide without breaking it apart. Perhaps I’ll try pre-searing next time.
For 2 servings:
250 grams (1/2 pound) cod fillet
125 ml (1/2 cup) white wine
125 ml (1/2 cup) home-made fish stock
1 fennel bulb
salt and freshly ground white pepper
Pre-heat the water bath to 54C/129F.
Clean the fennel and cut into strips. Sauté the fennel in some butter, season with salt and freshly ground white pepper and let braise covered for around 30-45 minutes over medium-low heat until golden brown. Stir now and then and make sure that it doesn’t burn, but on the other hand the taste will be enhanced if it is browned quite a bit as you can see in the final picture. At the end of the cooking, squeeze a bit of lemon juice on the fennel and stir.
Meanwhile, wash the cod fillet, pat dry with paper towels and season with salt and freshly ground white pepper.
Seal in a bag with a bit of butter and cook sous-vide for 30 minutes.
Meanwhile, chop the shallot and sauté it in a small saucepan in some butter until translucent.
Add the white wine and let reduce a bit over high heat, then reduce the heat and add the fish stock and let simmer without boiling to reduce to about one quarter of the original volume. Strain through a sieve and keep warm.
Pre-heat the plates.
Remove the fish from the bag and sear in very hot butter on all sides (try to keep as whole as possible, but fish will break).
Finish the sauce by whisking in a bit of cold butter off the heat. The sauce will thicken a bit, but not much.
Serve the fish with the sauce, a slice of lemon and the braised fennel.
Wine suggestion: this will go well with almost any dry white unoaked wine that is not too heavy as the taste of the fish is quite delicate.
