Hello! I decided to make strawberry freezer jam. I went and picked berries, got my ingredients ready, and went to work. I used Ball pectin and followed the recipe in the box, EXCEPT I used 1/2 as much sugar as the recipe called for because I tasted it and it seemed perfectly sweet.
This morning I was ready to have jam and it's liquid! The jam didn't set up. Maybe the sugar was for more than flavor? Can I salvage this by adding more pectin or sugar at this point? I would prefer more pectin, as I left out 4 of the 8 cups of sugar listed in order to have healthier jam. Any experience with this? HELP!
