Oh OK I see. Great video, I've been adding the mix to both sides of the filet. Maybe that's why it's so salty. You also use a lot less mix than I do. Still really good, my friends love it but your video helps.
Also the texture of the gravlax in the photo above (drier with a nice white finish) and in your video (like cold smoked lox) is very different. Did you just air dry it longer for the sample in the photo. The gravlax you made in the video looks awesome too..with some sliced red onion, some capers, dollop of cream cheese, a lemon wedge and a hardboiled egg, it'd be a perfect breakfast.
Between gravlax and indian candy, I'm going through fish at an astounding rate... this stuff is perfect as a snack while you're fishing in the cold..especially with some soda crackers.
