Balsamic Vinaigrette

A simple classic vinaigrette. This is a great jumping off point for other vinaigrettes. Simply substitute some part of the oil for other ingredients. Fruits like strawberries and lemon are good substitutions for part of the oil. If you go very sweet you may want to cut back on the mustard, but be careful; the main reason for using it is to improve the emulsion, so leaving it out can lead to vinaigrette separation after a while.
