As the name implies, Fiskfélagið is mostly known as a seafood restaurant. But their presentation of this lamb dish deserves note. The vapor is caused by cauliflower, which has been prepared in liquid nitrogen and is thus quite cold when it’s spooned onto the lamb. The full description is:
Grilled Leg of Lamb in Herbs, Smoked Loin of Lamb with Red Onion & Plum Tomato, Cauliflower Purée, Button Mushroom & Rosmarin Birch Sauce. From Kvelduhverfi.
