Another way to spark salad dressings is to use fruit juices to replace all or some of the vinegar. Doing so adds a different kind of edge -- a spark that's light, fresh, and fruity.
1. As a rule, start with one part juice to one part oil.
2. Season with salt and pepper, and experiment with other spices, herbs, and flavorings as desired.
3. With tart juices, such as lemon and lime juice, you can replace all the vinegar.
4. But if you use a less-tart juice -- such as orange, apple, or cranberry-raspberry juice -- team it with vinegar to bring both tartness and fruitiness to a vinaigrette.
