Learn How to Make Lox
Learn How to Make Lox
Oh, I think I have changed my mind on this subject.The link sure sounds like a gravlax recipe. I have not done much research, but many definitions on the internet seem incorrect. Some even allowing for lox to be smoked. I do not know why language has a tendency to involve so that distinction names for distinct products tend to blend together. Distinctions are useful. To me there is a difference between lox on one hand and Nova and smoked salmon, on the other, with gravlax being a third category.
Traditionally, I would say that lox was cured with only salt/brine, no sugar, and was not smoked. No spices or herbs of any kind. It is very salty fpor modern tastes. Nova is less intensely salted/brined and is cold smoked. I frankly do not know whether Nova historically had any sugar in the cure. If I was making cold-smoked salmon, I would have sugar in the brine. Gravlax is cured in salt, sugar, and dill, with juniper often added. No smoke. Gravlax is generally weighted while being cured. I do not know whether lox is weighted. As I recall, lox was cured for months. I do not think Nova or gravlax are generally cured for more than a few days.
I have told this story before on this subforum, but I endeavored to make gavlax from a beautiful fresh piece of salmon once. As I was preparing it, I noticed what looked like a white thread coming up out of the flesh. On closer examination, it was a tiny white worm of some sort, hollow, with a clearly articulated round mouth at one end. Now I assume that the cure would have killed this and any other parasites, and that I could have frozen the fish or simply cooked it and safely eaten it--I am sure most salmon this is never frozen or cooked has some live parasites--but it freaked me out, and I pitched the whole thing. A shame. It was a very nice piece of salmon.
As long as the salmon has been frozen at commercial temps, I do not think there is an issue, but I know how you feel!Oh, I think I have changed my mind on this subject.
There’s sashimi grade of fish..It been frozen for two months. Freezing kills any bugs.
I sure do!
A good friend of mine is Icelandic, and I use his family recipe.
Mix together generous amounts of brown sugar, coarse sea salt, and fresh dill. Rub well into the salmon fillets; wrap tightly in clingwrap, and place in container in refrigerator, stacking fillets flesh to flesh, with a moderate weight to press together (I use a hard-bound book). Leave for three days, turning stack(s) each day.
Bingo - perfect gravlax!
Here is a photo of my last batch heading off to the fridge.
Hi Ryan.This is really interesting! Can you provide an after pic once finished?
Hi Ryan.
I had a look back through my photos, but I don't seem to have an 'after' snapshot. I guess I'm too eager to eat it!
I can say that once it is cured, I slice it thinly before eating, and ensure that the no skin is attached to the slices.
Next time I do a batch, I will post an 'after' photo.
Now I assume that the cure would have killed this and any other parasites, and that I could have frozen the fish or simply cooked it and safely eaten it
Yeah, I need to amend my original statements. I do not think I had anything available to me that would freeze the fish at a low enough temperature to render it safe, and I really have no idea whether the cure would have either!The standard is -4F for seven days, or -31F for 15 hours. Freezing at 32F, for any length of time doesn't kill the parasites.
