I called Ener-G to ask about the shelf life, which they told me was 3 years. I bought mine in 2016, but the tag on the jar says best used by 1-23-18. What is the shelf life and is mine still effective?
Hello, the expiration dates are three years out from manufacture date. So that particular batch must have been made in 2015. What we have been told to test the baking soda is to add some to a bowl and add in some vinegar or lemon juice (something acidic). If it fizzes/reacts then it is still good!
