Mason jars are perfect for salad dressing recipes. With glass, you don’t have to worry about any nasty chemicals leaking into your food from unsafe plastics, and they’re easy to wash and reuse. They're also dishwasher safe. If you buy the mason jars with a wide mouth, you can even get a utensil down in the jar! Plus, the ring and lid seal tightly, so you can give the jar a good shake before using your healthy salad dressing.
