Sorry if that's not the information you're looking for but here it goes on case it could be useful to you:
I make my own jam by putting a few frozen strawberries, or other frozen berries, in the microwave. Once they're soft, not even warm, but softened, I mash them with a fork, or with a hand mixer, than I use it as jam. Sometimes I mix with a bit of chia and put in the fridge until the chia softens. It makes a thicker jam. They're sweet enough that I don't need to add sweeteners, but you could add any sweeteners of your choice to get it more sweet. I've tried with sweeteners and it was fine. It's quickly done and you can keep it in the fridge for a few days, or make it everytime you need it.
I hope you find everything you want.
