Sebastes mentions Gravlox...I have tried making it twice. The first time I made it, I followed a free recipe I found on YOUTUBE, some series named "COOKING COARSE". It was wonderful! Very easy, came out just like the best Lox I ever had. Perfect. The stuff was to die for!
Basically its like a salt and sugar dry-rub on your fillets, then cover all over with fresh dill, wrap in plastic, put weight on top and leave in refrigerator until juices quit coming out...seems to me it was about a week you had to leave it. Mine turned out great. That was when I had a recipe to follow.

Fast forward a couple years, I thought about making some again. Couldn't remember the recipe, so went back on YOUTUBE to find it. Remembered "COOKING COARSE", found out that what used to be free was not, and now you had to pay for their whole series of videos. "Screw that" I thought so I just decided to wing it. Bad idea! It did not turn out edible at all. I must have been off in my ratios of salt to sugar is the only thing I can think. Or maybe forgotten one step or something.

Anyways, there are other Gravlax recipes out there, and if you do it right it turns out damn good. I just wish I didn't have to pay for that original recipe I saw. It was so basic and easy. The other recipes I've seen seem much more complicated for some reason. I just need to search around some more.
