At the end of this course you will be able to:
Take four fillets off a turbot by cutting along the backbone from head to tail.
Salt the turbot first, then add very cold cream little by little and pass the farce through a sieve.
Roast a sole on the bone to a core temperature of about 42°C, basting it with browning butter.
Fill a whole sea bass with herbs and lemon, flour it lightly, sear it and finish it in the oven.
About this class
This online fish cooking class covers five fish in 15 lessons, starting with how to judge freshness: clear eyes, red gills and flesh that springs back. Salmon gets the most time: cured in salt and sugar with herbs, fennel seed and star anise, it becomes a tartare, a herb-crusted tranche and flamed slices with wasabi.
Four of the five fish are filleted on camera. The turbot carcass goes into a fish stock and the trimmings into a farce for the sole rolls. The last lessons roast a sea bass whole and cook red mullet with its scales on until they turn crisp.

“The big advantage of frying fish on the bone is that it remains juicier.”
