Traditionally, vinegar is what gives vinaigrette its bite, but you can use fruit juices to replace some of the vinegar for a new flavor.
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.
