Next time you grab a bottle of salad dressing off the shelf, read the ingredients. It may alarm you that something so simple has so many ingredients that you’ve probably never heard of. Some keep the dressing from spoiling on the shelf while others are used to improve texture. While some may be harmless, it's easy to avoid them if you make your own dressing at home. A simple dressing takes no more than 10 minutes to make and is as easy as whisking oil into vinegar and throwing in a few seasonings like garlic powder, Dijon mustard and minced garlic or shallot. Making your own dressing can help you control calories too. If you find a recipe you like, double it so you can keep some in your refrigerator to use throughout the week.
