Use this vinaigrette by itself, or dress it up with some special additions. For an aggressively flavored salad, add garlic and serve with strong greens like arugula and chicory. Add chopped shallots to jazz up sliced mushrooms or green beans. Add capers and minced red onion to enhance warm boiled potatoes. Fold in fresh tarragon and spoon over asparagus. Or mix in basil and crumbled goat cheese, then serve over sliced tomatoes.
Mix all ingredients in a nonreactive jar. Shake well to combine. Store airtight and refrigerated until ready to use.
