With 60 pounds of tomatoes staring at me this morning, I got started,
only to discover that there is no citric acid left in the cupboard. So
far I've used lemon juice just to be sure. However, I do have a good
sized bag of powdered ascorbic acid. I know it is stronger than citric
as far as being an antioxidant, but how does it compare as an acid? Can
I substitute ascorbic for citric in canning tomato sauce and paste?
