What is Onion Salt?
Onion salt is a convenient substitute for chopped onions. It’s useful when you don’t have the time to prepare chopped onions, or want to add onion flavor to a dish without the bulk of additional ingredients. Most onion salt is made with a combination of dehydrated powdered onions and salt, and usually a preservative ingredient that keeps the powder and salt from adhering to each other. This seasoning should be differentiated from onion flakes or onion powder, which do not contain salt. The ratio of table salt to powdered onion is about three to one. If you are looking for lower salt foods, you probably shouldn’t choose onion salt, since a quarter teaspoon (about 1.4 grams) has almost as much sodium as does regular table salt. Average sodium content in onion salt is about 450 milligrams as opposed to the 575 mg offered in the same size serving of table salt. Alternately, simply remember that onion salt does contain salt and lower additional salt in your recipes when you use it.
