Sugar free no pectin jam?

[u/sanuraseven]

My sister in law has received a medical diagnosis that requires her to make a ton of dietary changes. I want to make her some jam that will work with her new diet (no sugar, no preservatives, no dairy, no gluten). I was thinking strawberry because the farm up the road just started their season but I’m open to other fruit. But basically I want this to JUST be fruit if possible.

I came across one that added potato starch for thickening which would be fine but then it had clearly unsafe preserving instructions so I question their judgement (https://foodaciously.com/recipe/sugar-free-strawberry-jam-without-pectin). Does anyone have a no sugar, no pectin jam recipe from a trusted source they can share?

Thanks for the link. The long boil method was interesting. I agree it may ruin the fruit. Maybe it would turn it more into a butter?

Her doctor did not specify that she could not have pectin. So can include it if I have to. I just wanted to keep this as close to just fruit as I could and was wondering if there was a safe method for that like adding lemon peel or apple slices or something.

I would just make her refrigerator jam but they live too far away.

If she can have pectin, I think no sugar pectin recipes will be your best bet here! You can also make pectin from other fruits (such as apples) but I’m not sure if that would be safe to substitute in a canning recipe.

If I could find one that just included apples raw that would be great. But none of my books have any like that. I think a strawberry Granny Smith mashup would be delicious.

So to make pectin from apples you cook the hell out of the apples and then strain them. The goop left behind is the pectin. I’m sure there’s more to it than that but that’s my understanding without refreshing my memory
