It may or may not be jam but it's not really a fail if you can still use it as syrup.So is it a fail ? or will it jam ?
I hope it will set up enough for you to be jam though, time will tell. I'd give it three days after processing and see.
I made Blackberry Syrup a few years ago and it went fast! It's so good on pancakes and waffles... and probably vanilla ice cream.
