Made a huge mistake while making gravlax (salt cured fish)

or salmon cakes mixed with mashed potatoes.

Should add – if it’s only cured around 2 days at this point, you might try rinsing well, patting dry and curing another 1-2 days with just sugar (or sugar and very little salt) plus more of whatever other flavoring you used – dill, juniper, vodka, gin, etc. (If it’s already been 4 days, a longer cure might make it mushy.) Also, I usually serve gravlax with just a dab of mustard/dill sauce…but if it’s extra salty, you might be able to balance it that way - rinse/slice very thin and serve with, e.g., cream cheese on a bagel, or on black bread thickly spread with unsalted butter, or with egg salad, or draped over a cucumber/dill/sour cream salad...all are delicious with very salty/fishy foils.

Only 2 days, I had already sliced it before I realized my mistake. Already started curing it in the sugar, so I guess we'll see how it turns out. Thank you very much for the help :D

It was incredibly salty, it was kinda fine but after a few bites it's too much. I was thinking of putting in sugar, not sure that it'll work but probably worth a shot.

You could try adding some sugar on a couple of slices, curing overnight to see if it improves.

If that doesn't do enough for you to enjoy, I'd consider cooking the rest, flake into small pieces, then freeze/save for other preparations to be mixed with larger quantities of other ingredients (don't use salt at first in those dishes).

One example might be fried rice.

Good luck.

Will do, in any case I'll post the results for future reference. thanks a lot :)
