I made some traditional Gravad Lax last year,only with a 5lb Rainbow trout instead of Salmon,and used beetroot powder in the cure (Hmm,not that traditional then)
I didn't like it at all ,as the beetroot powder added an overpowering earthiness.
Was a lovely colour though.
Give a man a fish,and you feed him for a day.
Teach a man to fish,and you won't see him again for the rest of the season.
