This is the traditional sauce for gravlax. It isn't easy to make, the first time you might not get it right but after a while you will. All it takes is not to give up and do everything slowly to start with. It is really worth the effort because it just makes the gravlax even better. In my family we use 2 tablespoons of honey mustard and 1 tablespoon of French unsweetened mustard.
