The only ones I found so far that taste pretty good and feels like your eating a sweet jam with good flavor, and it does not taste like a sugar free is orange marmalade.
But Orange marmalade flavor does not go with everything if you want to use it as a filling or to bake with.
So I been making my own at home and so far they are pretty tasty, I had an extra bags of grapes in the fridge the other day that no one wanted to eat, instead of tossing them in the trash I made jam out of them! and I ended up with two jars out of 3 lbs. of green grapes and one jar of red grapes, about a 1 1/2 lbs. not bad at all!!
Tomorrow I am baking a coffee cake and planning on using some of these tasty jam as the filling.
