Gravlax with mustard-dill sauce
Along the coasts of Norway and Sweden, gravlax is the centrepiece of Christmas and Easter buffets and a favourite on open sandwiches through the year. A side of salmon is pressed under salt, sugar, dill and white pepper for two days in the fridge, which firms the flesh and turns it silky, then it is sliced paper-thin and served with a sweet mustard-dill sauce, rye bread or boiled new potatoes. This is cured, not cooked, fish: use very fresh salmon that has been previously frozen (or freeze it yourself at -18 °C for at least 4 days, then thaw in the fridge) to kill any parasites, and it is not suitable for pregnant women, young children or anyone with a weakened immune system. A frequent error is slicing it thick and straight down; cut long, thin slices at a low angle towards the tail. Chef's tip: turn the parcel every 12 hours and baste with the brine it releases so the cure is even on both sides.
