What should I do if my strawberry jam does not seem to reach setting point?
Strawberries are naturally low in the setting property pectin. If your jam won't set, tip it back into the pan, add the juice of a small lemon to give the jam extra pectin, bring it back to the boil for five minutes and test again for a set. If this does not seem to work, continue to boil the jam, testing for a set every two minutes. I do believe there should never be any need to use commercial 'setting agents'.
