Turkish delight

I tried this and got to 115 degrees but couldn't get it to softball at that temp, didn't want to take the temp too high so gave up at 118 degrees and turned it off. Continued with recipe, smelt just like real turkish delight when added the rose water. Unfortunately not really set firmly enough, it's still sticky rather than stringy and doesn't taste of rosewater. Any suggestions, I've seen so many diff variations on the temperature, anyone got the correct one. I would love for this to turn out right! This is second attempt after trying James Martin's recipe and burning it because website set wrong temp! Thanks
