Always check your vinegar
Yesterday I was going to pick up some vinegar at the local grocery store. When I got there, I grabbed the off-brand because it was on sale. Then I thought to myself that I just better check the acitity level, just in case. Was I ever glad I did. It was marked 4% acidity!!! Are manufacturers really that desperate they have to dilute the vinegar to try and make a few extra pennies? Shame on them!
