Out in the last minut without Gravlax on your cristmastable?
If you have an vacummachine and some salmon, that will sort out very fast. Put the fish and whatever your want, whisky, dill, whitepepper with salt and very little sugar in the plasticgbag and just vacum it with high pressure. Dont use table salt but grainsalt. The pellets will shoot into the fish by the pressure and you will have the fish ready in 10-12 hours. The fish will be in the bag till servingtime and the salt will not dry it out so fast because of that, so there is no need for so much sugar. Yummy!
