I love salmon sushi above all, I could probably eat that every day. There is something so luxurious about raw salmon, yum.
I also cook it at home. I pan sear it in a skillet and cook until medium. Remove to the side. To the drippings in the pan add a splash of vermouth, a tbsp of dijon mustard, a shot of heavy cream and some fresh herbs (parsley/dill/scallion/chives all work). Reduce the sauce a little bit, then add a pat of butter to it and serve over the salmon.
I also love poaching salmon. In a pan I sautee chopped shallot and garlic until soft. Then I add some vermouth or dry white wine, and a cup of vegetable broth and bring to a simmer. Gently place the salmon in the poaching liquid and cover. Do not boil! When the salmon is done to your desired liking (medium for me) remove the salmon. Reduce the sauce, add a pat of butter and a squeeze of lemon juice and serve over the salmon.
