Contrary to what you might expect, Balsamic vinegar has a sweet, almost fruity taste and none of the acidic characteristics usually associated with vinegars. It adds a surprising flavor to sautéed spinach.
1-1/2 pounds spinach
3 tablespoons olive oil
3 tablespoons water
Salt and freshly ground black pepper
4 tablespoons Balsamic vinegar
2 tablespoons red wine
6 tablespoons cold butter, cut into 12 pieces
1. Rinse the spinach and remove the tough stems. Tear any large leaves in half and set aside.
2. Heat the oil in a large skillet or wok. Add the spinach and stir over high heat until wilted. Sprinkle on the water. Reduce the heat to low and cover the pan. Cook for 2 to 3 minutes or until the leaves are tender. Season with salt and pepper.
3. Meanwhile, combine the vinegar and wine in a small saucepan. Place over medium heat and cook until reduced by half. Remove from the heat and whisk in the butter, one piece at a time. Pour over the spinach to serve.
