This has been my favorite quick and easy salmon recipe for years! I love the salmon's crispy skin and medium rare center, and the vinaigrette makes the perfect compliment. I spoon a little of the vinaigrette on each bite of salmon and drizzle it over a side dish of roasted asparagus. I adapted a Gourmet recipe by reducing the amounts of Dijon and horseradish in the original vinaigrette, which called for 4 tablespoons of each. If you can find tarragon white wine vinegar, just toss in some fresh parsley for the herbs. Please use very fresh salmon. p.s. You don't have to eat the skin, but I do recommend cooking it with the skin on to protect the tender salmon.
