Here is what I did; I ordered Xyla sweetener from Amazon, a bit expensive but does not ferment. It's a one for one sugar substitute.
Dissolved the Xyla and priming sugar in very hot water (190°), added to hard cider, stirred it in, and then bottled in beer bottles. I used 1 cup of Xyla and 1/3 cup priming sugar for 3 gallons of hard cider.
No sorbate or potassium meta sulfite or you won't get carbonation.
I did use sulfite in the primary but none after that. Was extra careful to clean and sanitize everything.
I read up on the pasteurization method but couldn't get by the "bottles may blow up" part. That along with the timing issue of having to do the pasteurization when the carbonation is at the right level. I can't always drop what I'm doing to pasteurize.
