Gravadlax, also known as gravlax, is a Scandinavian dish consisting of fresh, raw salmon fillet marinated with salt, sugar and dill. Once cured, it’s sliced thinly. It originated as a means to preserve fish in the days before refrigeration. The fish was prepared with salt and dill and then buried in the ground. (‘Grav’ is Swedish for ‘grave’ or ‘pit’. ‘Lax’ is Swedish for ‘salmon’.)
These days it can easily be made at home in the fridge. Using beetroot in the cure has become fashionable and gives the salmon an interesting colour. The Not Delia website has a delicious take on this using a fresh orange, honey and soy sauce.
