Very timely grisell, I've got the sloes off my last years sloe gin to use up!
John, trust you, I hate making strawberry jam, I find it one of the hardest!
In all honesty, you've picked a lousy time to start, the main 'jam fruit' season's over. As to canned fruit - Pass!
I held of posting a reply as I have posted an item on my blog today about the 'Autumn Curd' (Well, OK, Marrow Curd) - this may be a good starting point - I believe it can also be made with pumpkin.
In the meantime, I hope someone else will explain the intricacies of strawberry jam (strawberries are low in pectin - hence possible problems). But most jams are some variation of 1:1 fruit to sugar. Cook fruit (if necessary), add sugar, melt sugar, bring to boil, boil till setting point reached, bottle. Dead easy in theory, but in my experience not always so easy in practice.
Mike D was a bit of a 'dab hand' at it! As is Ianinfrance by the look of it. (plus others no doubt)
