This is a variation on a classic French dish made with Madeira wine and heavy cream that I found while thumbing through Larousse Gastronomique. I like Marsala wine a bit better and it is what I had on hand. For the dish you will need:
Two salmon filets
1 tsp. of butter
4-5 dried shiitake mushrooms
1/2 cup of Marsala wine
1/4 cup heavy cream
Juice of one lemon
Parsley and/or chives for garnish
First, salt the salmon well and set aside. In a bowl, pour boiling water over the dried mushrooms and let them soak for at least half an hour. You can use fresh mushrooms of your choice here. I like to use dried now and again because they have an earthiness and depth of flavor not found in fresh mushrooms. They can overwhelm a dish if you’re not careful, but since I was dealing with a rich fish with sauce I felt they could really add something.
Remove the mushrooms from their bath and remove the stems. Slice the caps in about 1/4 inch slices. Heat some olive oil and the butter on medium high heat. Dredge the salmon in the flour, add it to the pan and reduce heat to medium. Add the mushrooms and sauté a few minutes on each side. You want a nice crust. Remove the salmon from the pan. Deglaze the pan with the wine. Be sure to scrape the pan to get all the flavor from the salmon. Reduce the wine by about half and add the heavy cream and lemon juice with the pan off of the heat. Whisk continuously to avoid separation and curdling. Add the salmon back to the pan and cover in the sauce. Plate with some green garnish (I used chopped flat-leat parsley) and potatoes on the side.
For the potatoes:
On a mandolin (or with a knife if you have way more patience than I do) slice a potato on the thinnest setting possible. You should be able to see through them. Chop a carrot finely and put a bit of carrot on a slice of potato. Take another slice of potato and sandwich in the carrot. Fry these in vegetable oil until crispy. Salt and serve on the side. The carrot here is more for visual accent. You can try this with just about anything (meat, shrimp, mushrooms etc.).
This dish is gluten-free other than the dredging flour. You could easily use gluten-free flour as a dredge.
