This is an extremely easy jam - in fact it was my first, teach yourself, jam experiment, and it worked brilliantly.
It was also very tasty! But as you can see below, I actually used frozen berries.
My notes on the recipe show:
1. Used 10g of Jamsetta to c.+/- 300g of fruit; frozen strawberries in microwave to defrost first. V. sweet! V. good!
2. With frozen fruit, add at least another two minutes to cooking time.
Please note that this recipe only takes 12 minutes, with the suggestion that you check the gelling, and if need be, add an extra couple of minutes until it's done.
Bloddy brilliant!! ;-)
