All you do is take some salmon and coat it with salt, sugar and herbs and wrap it tightly and place it in the fridge. Turn it twice a day for 3-4 days and voila, you have gravlax! It tastes better than bought gravlax and isn't frozen like a lot of gravlax or smoked salmon can be. I gave some to half Scandi Mr NQN and he adored it and I had to stop him from devouring the fillet just as his ancestors may have done too.
