Dorado has several culinary advantages: its white meat has a delicate flavor and it has few bones. The tastiest dorado will turn out when it is cooked whole, but eating fish in this form is not very convenient. The chef of the Mercedes bar restaurant, Artem Sergeev, makes an imitation of a whole fish by wrapping the fillet in nori leaves.
Cut the dorado into boneless fillets, cut each fillet in half lengthwise. Brush nori leaves with soy sauce until soft. Wrap a quarter of a fillet in each leaf. Put in a double boiler for 10 minutes.
Mix all sauce ingredients except oil. While constantly whisking the sauce, add truffle or olive oil. Serve the sauce separately.
