I have some surplus cooking apples which I will be trying to make jam with. I can't find pectin in my local supermarket, but they do have "jam sugar", which contains pectin, but is twice the price of regular sugar.
From what I've read, apples are a natural source of pectin. So do I need to add extra pectin to my jam in order for it to set?
FYI: I don't have any crab apples, which people have suggested adding to jam to hep it set.

Yes. See the accepted answer for Can most sour fruits be jelled by cooking with sugar?. After getting that answer, I have successfully made apple jelly with fresh cooked and strained apple juice and sugar, and nothing else. You can search for apple jelly recipes and find directions.
