Black Truffle Vinaigrette
Bon Appetit January 2005

* 2 ounces fresh or jarred black truffles
* 1/2 cup Tuscan-style extra-virgin olive oil, divided
* 1/4 cup minced shallots
* 1 cup Cabernet Sauvignon or other dry red wine
* 2 tablespoons Banyuls vinegar**( I used balsamic)
* 1 tablespoon fresh thyme leaves
* Coarse kosher salt

For vinaigrette:

Thinly slice truffles, then dice finely. Heat 1 tablespoon oil in small skillet over medium heat. Add shallots; sauté 2 minutes. Add truffles and sauté until aromatic, about 1 minute. Place shallot mixture in small bowl.
Boil wine in heavy small saucepan until reduced to 2 tablespoons, about 10 minutes. Add to shallot mixture. Whisk in vinegar and thyme. Gradually whisk in remaining 7 tablespoons oil. Season vinaigrette to taste with coarse salt. (Can be made 2 hours ahead. Let stand at room temperature.)
